+This is only a summary provided to give a quick overview of changes. It does not list details which can be found in commit messages. If you think that more detailed changelog would be beneficiary, please raise it as an issue.
+
+Versions marked as 'unofficial' are labelled only for the needs of this changelog. Officially I maintain version numbers since 2019/04, starting from version 1.14. If you have any of the earlier commits then you will see plugin signed as a version 1.0.
+
+Change History
+--------------
+
+Version: 1.22 (2021/04)
+- Fixed potential for initialization fiasco when using delegates container.
+- Fixed bug in code protecting redirecting handles from self-referencing.
+- Fixed cached resource handles getting invalid after reloading texture resources.
+
+Version: 1.21 (2020/07-09)
+Improving stability
+- Fixed a crash in the input handler caused by invalidated by hot-reload instance trying to unregister a delegate.
+- Improved hot-reload stability and support for reloading after recompiling outside of the editor. Both methods should be equally supported and work together.
+- Improved behaviour of delegates when hot-reloading.
+- Changed context index mapping to fix issues with multi-PIE debugging in 4.25.
+- Fixed Linux crash caused by wrong mapping of key codes.
+
+Version: 1.20 (2020/06)
+Transition to IWYU and maintenance:
+- Replaced includes of monolithic headers.
+- Removed explicit PCH and switched to IWYU-style PCH model.
+- Fixed includes to compile without explicit PCH in non-unity mode.
+- Fixed a few issues causing compilation errors in older engine versions.
+- Fixed debug code to compile on platforms using other than char or wchar_t characters.
+- Fixed issues in recently added DPI scaling.
+- Cleaned obsolete and unused code.
+- Replaced custom scope guards with the template provided by the engine.
+
+Version: 1.19 (2020/03-06)
+- Integrated fix for issue with ImGui popup/modal windows not being able to be closed in transparent mouse input mode. 
+- Integrated first version of Adaptive Canvas Size.
+- Added different options to define canvas size, with Adaptive Canvas Size being one of the options (viewport).
+- Added option for DPI scaling.
+
+Version: 1.18 (2020/01)
+- Updated to engine version 4.24.
+- Updated to ImGui version 1.74.
+
+Version: 1.17 (2019/04)
+- Added experimental support for touch input.
+- Integrated fixes allowing to build this as an engine plugin:
+- Added support for sharing with game mouse input.
+- Refactorization of input handling, with changes in SImGuiWidget and compatibility breaking changes in UImGuiInputHandler.
+
+Version: 1.16 (2019/05)
+- Fixed issue with SImGuiLayout blocking mouse input for other Slate widgets, which was introduced by refactorization of widgets (version 1.14, commit c144658f).
+
+Version: 1.15 (2019/04)
+- Added new FImGuiDelegates interface for ImGui debug delegates.
+- Added code preserving delegates during hot-reloading and moving them to a new module.
+- DEPRECIATED old FImGuiModule delegates interface and FImGuiDelegateHandle.
+- Delegates registered with depreciated interface are redirected and get benefit of being preserved during hot-reloading. This can be controlled with IMGUI_REDIRECT_OBSOLETE_DELEGATES.
+- Added IMGUI_WITH_OBSOLETE_DELEGATES allowing to strip depreciated interface from builds (that interface will be officially removed in one of later releases).
+- Added new ImGui early debug delegates called during world tick start.
+- Delegates are called in fixed order: multi-context early debug, world early debug (called during world tick start), world debug, multi-context debug (called during world post actor tick or if not available, during world tick start).
+- Removed from build script configuration of debug delegates.
+
+Version: 1.14 (2019/03)
+- Added SImGuiLayout to resets layout for SImGuiWidget.
+- Refactored rendering in SImGuiWidget to take advantage of layout reset.
+- Reworked ImGui canvas dragging and scaling and moved it to SImGuiCanvasControl.
+- Removed dependency on ImGui internal cursor data.
+
+Version: 1.13 (unofficial) (2019/03)
+- Fixed mapping from FKey to ImGui key index to gracefully handle unsupported keys and work on platforms that do not support all the keys defined in ImGui key map.
+- Fixed non-unity compile warnings and errors. 
+
+Version: 1.12 (unofficial) (2018/12)
+- Added support for sharing with game keyboard and gamepad input.
+- Added FImGuiModuleSettings to handle delayed loading of UImGuiSettings and serve as settings proxy for other classes.
+
+Version: 1.11 (unofficial) (2018/10-11)
+- Moved ImGui Draw events to be called at the end of the world update during post actor tick event. Only available in UE 4.18 or later, with old behaviour available as an option.
+- Replaced console variable based configuration of ImGui Draw events with macros.
+- Replaced console variable based configuration of software cursor with a setting.
+- Console variables and logging that are primarily focused on module development are hidden by default and can be enabled by setting IMGUI_MODULE_DEVELOPER to 1.
+- Replaced console variables with module properties and settings.
+- Added console commands to control module properties.
+- Added support to preserve and move module properties to hot-reloaded module.
+- Moved properties to public interface.
+- Added FImGuiModule interface to access properties instance.
+- DEPRECIATED FImGuiModule functions to modify single properties.
+
+Version: 1.10 (unofficial) (2018/10)
+- Changed module type to 'Developer' to make it easier strip it from shipping or other builds.
+- Added runtime loader to allow automatically load developer module in runtime builds.
+
+Version: 1.09 (unofficial) (2018/08-09)

+Unreal ImGui
+============
+
+[![MIT licensed](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE.md)
+
+Unreal ImGui is an Unreal Engine 4 plug-in that integrates [Dear ImGui](https://github.com/ocornut/imgui) developed by Omar Cornut.
+
+Dear ImGui is an immediate-mode graphical user interface library that is very lightweight and easy to use. It can be very useful when creating debugging tools.
+
+Status
+------
+Version: 1.22
+
+ImGui version: 1.74
+
+Supported engine version: 4.26*
+
+\* *Plugin has been tested and if necessary updated to compile and work with this engine version. As long as possible I will try to maintain backward compatibility of existing features and possibly but not necessarily when adding new features. When it comes to bare-bone ImGui version it should be at least backward compatible with the engine version 4.15. For NetImgui it needs to be determined.*
+
+Current work
+------------
+
+Currently, I'm a little busy outside of this project so changes come slowly. But here is what to expect in the reasonably near future:
+- Stability first, so fixes for more critical issues like an invalidation of handles after reloading texture resources will be pushed first. The same goes for merges.
+- There are a few smaller issues that I'm aware of and that might be not reported but which I want to fix.
+- ImGui needs to be updated.
+- Smaller features might be slowly pushed but bigger ones will need to wait. The same goes for merges.
+- There is a branch with NetImgui which is really good, and which will be eventually merged to master, but first I want to fix a few issues that I know about (some are discussed in thread #28). In the meantime, the NetImgui branch is pretty much ready to use.
+
+
+About
+-----
+
+The main goal of this plugin is to provide a basic integration of the Dear ImGui which will be easy to use from the game code.
+
+My main focus used to be on debugging and for that this plugin should work out of the box. It is possible to use it for different purposes but depending on the use case it may require some adaptations.
+
+To support multi-PIE, each world gets its own ImGui context to which it can draw. All that is managed by the plugin in a way that should be invisible for the game code. I plan to extend it to allow own contexts and widgets but right now I don't have enough time to commit to that.
+
+As of recently, the plugin has the *net_imgui* branch with an integration of the [NetImgui](https://github.com/sammyfreg/netImgui) developed by Sammyfreg. This is still experimental, but it is possible to already download and use it. Many thanks for the library and for the initial integration.
+
+### Key features
+
+- Multi-PIE support with each world getting its own ImGui context.
+- Automatic switching between different ImGui contexts.
+- Delegates for functions with ImGui content.
+- Support for Unreal textures.
+
+How to Set up
+-------------
+
+To use this plug-in, you will need a C++ Unreal project.
+
+### Installation
+
+Content of this repository needs to be placed in the *Plugins* directory under the project root: *[Project Root]/Plugins/ImGui/*. After you compile and run you should notice that *ImGui* module is now available.
+
+Note that plugins can be also placed in the engine directory *[UE4 Root]/Engine/Plugins/* but I didn't try it with this project.
+
+If you want to use NetImgui, instead of please look at the [How to Set up NetImgui](#how-to-set-up-netimgui).
+
+### Setting module type
+
+The *ImGui* module type is set to **Developer**, what means that if it is not referenced by other runtime modules, it can be automatically excluded from shipping builds. This is convenient when using this plugging for debugging but if you want to change it to other type, you can do it in module description section in `ImGui.uplugin` file.
+
+**Developer** type was depreciated in UE 4.24. I keep it for backward compatibility while I can, but if you get a UBT warning about module type, simply change it to **DeveloperTool** or **Runtime**.
+
+### Setting up module dependencies
+
+To use ImGui in other modules you need to add it as a private or public dependency in their Build.cs files:
+
+```C#
+PrivateDependencyModuleNames.Add("ImGui");
+```
+
+or
+
+```C#
+PublicDependencyModuleNames.Add("ImGui");
+```
+
+You might also want to use ImGui only in certain builds:
+
+```C#
+if (Target.Configuration != UnrealTargetConfiguration.Shipping)
+{
+	PrivateDependencyModuleNames.Add("ImGui");
+}
+```
+
+### Conditional compilation
+
+You can conditionally compile ImGui code by checking `IMGUI_API`:
+
+```C++
+#ifded IMGUI_API
+#include <imgui.h>
+#endif
+
+// ... somewhere in your code
+#ifded IMGUI_API
+// ImGui code
+#endif
+```
+
+Above code is fine but it requires wrapping include directives and does not follow the usual pattern used in Unreal. To improve that, you can add the following code to one of your headers (or a precompiled header, if you use one):
+
+```C++
+// ImGuiCommon.h
+#pragma once
+
+#ifdef IMGUI_API
+#define WITH_IMGUI 1
+#else
+#define WITH_IMGUI 0
+#endif // IMGUI_API
+
+#if WITH_IMGUI
+#include <imgui.h>
+#endif // WITH_IMGUI
+```
+
+And then use it like this:
+
+```C++
+#include "ImGuiCommon.h"
+
+// ... somewhere in your code
+#if WITH_IMGUI
+// ImGui code
+#endif
+```
+
+How to Set up NetImgui
+----------------------
+
+To use NetImgui, use content of the *net_imgui* branch in place of *master*. This will be gradually merged into the *master* but until then you need to use that experimental branch.
+
+Similarly like ImGui, NetImgui is built as part of the UnrealImGui plugin and no other integration steps are required.
+
+To be able to connect to the Unreal editor or application that use NetImgui, you need to run a server (netImguiServer). Please, see the [NetImgui](https://github.com/sammyfreg/netImgui) page for instructions how to get it.
+
+After launching the server for the first time, you need to add two client configurations, for ports 8889 and 8890. After that, you can either initialise connection from the server or set it to autoconnection mode. More info will be added later.
+
+Once you establish connection, you can use a top bar to switch between contexts and modes. In standalone game it should be one context and in the editor one editor context, plus one for each PIE instance.
+Please, note that all those features are experimental and might evolve. Any input is welcomed.
+
+How to use it
+-------------
+
+### Using ImGui in code
+
+ImGui can be used from functions registered as ImGui delegates or directly in game code. However, if code is running outside of the game thread or is executed outside of the world update scope, delegates are a better choice.
+
+Delegates have an additional advantage that their content will work also when game is paused.
+
+### ImGui Delegates
+
+To use ImGui delegates, include `ImGuiDelegates.h`.
+
+There are two major types of ImGui delegates: world and multi-context. First are created on demand for every world and are cleared once that world becomes invalid. They are designed to be used primarily by worlds objects. In opposition, multi-context delegates are called for every updated world, so the same code can be called multiple times per frame but in different contexts.
+
+Delegates are called typically during world post actor tick event but they have alternative versions called during world tick start. In engine versions that does not support world post actor tick, that is below 4.18, all delegates are called during world tick start.
+
+Delegates are called in order that allows multi-context delegates to add content before and after world objects:
+- multi-context early debug
+- world early debug
+- world update
+- world debug
+- multi-context debug.
+
+> `FImGuiModule` has delegates interface but it is depreciated and will be removed soon. Major issue with that interface is that it needs a module instance, what can be a problem when trying to register static objects. Additional issue is a requirement to always unregister with a handle.
+
+### Multi-context
+
+In multi-PIE sessions each world gets its own ImGui context which is selected at the beginning of the world update. All that happens in the background and should allow debug code to stay context agnostic.
+
+If your content is rendered in the wrong context, try using one of the [ImGui delegates](#imgui-delegates) that should be always called after the right context is already set in ImGui.
+
+### Using Unreal textures
+
+Unreal ImGui allows to register textures in order to use them in ImGui. To do that, include `ImGuiModule.h` and use `FImGuiModule` interface.
+
+After registration you will get a texture handle, declared in `ImGuiTextureHandle.h`, that you need to pass to the ImGui API.
+
+```C++
+// Texture handle defined like this
+FImGuiTextureHandle TextureHandle;
+
+// Registration and update
+TextureHandle = FImGuiModule::Get().RegisterTexture("TextureName", Texture);
+
+// Release
+FImGuiModule::Get().ReleaseTexture(TextureHandle);
+
+// Find by name
+TextureHandle = FImGuiModule::Get().FindTextureHandle("TextureName");
+
+// Example of usage (it is implicitly converted to ImTextureID)
+ImGui::Image(TextureHandle, Size);
+```
+
+### Input mode
+
+Right after the start ImGui will work in render-only mode. To interact with it, you need to activate input mode either by changing `Input Enabled` [property](#properties) from code, using `ImGui.ToggleInput` [command](#console-commands) or with a [keyboard shortcut](#keyboard-shortcuts).
+
+#### Sharing input
+
+It is possible to enable input sharing features to pass keyboard, gamepad or mouse events to the game. Note, that the original design assumed that plugin should consume all input to isolate debug from game. While sharing keyboard or gamepad is pretty straightforward and works by passing input events to the viewport, mouse sharing works in a bit different way. Since the ImGui widget overlays the whole viewport, widget needs to switch hit visibility and update position in the background. It might be possible to generate a custom collision geometry matching ImGui and simplifying working with mouse and touch inputs, but I don't plan to work on this right now.
+
+The default behaviour can be configured in [input settings](#input) and changed during runtime by modifying `Keyboard Input Shared`, `Gamepad Input Shared` and `Mouse Input Shared` [properties](#properties) or `ImGui.ToggleKeyboardInputSharing`, `ImGui.ToggleGamepadInputSharing` and `ImGui.ToggleMouseInputSharing` [commands](#console-commands).
+
+#### Keyboard and gamepad navigation
+
+When using ImGui on consoles you most probably need to enable keyboard and/or gamepad navigaiton. Both are ImGui features that allow to use it without mouse. See ImGui documentation for more details.
+
+You can toggle those features by changing `Keyboard Navigation` and `Gamepad Navigation` [properties](#properties) or using `ImGui.ToggleKeyboardNavigation`and `ImGui.ToggleGamepadNavigation` [commands](#console-commands).
+
+#### Navigating around ImGui canvas
+
+Most of the time ImGui canvas will be larger from the viewport. When ImGui is in the input mode, it is possible to change which part of the canvas should be visible on the screen. To do that press and hold `Left Shift` + `Left Alt` and use mouse to adjust.
+
+- `Mouse Wheel` - Zoom in or out.
+- `Right Mouse Button` - Drag canvas with ImGui content.
+- `Middle Mouse Button` - Drag frame representing which part of the canvas will be visible after ending the navigation mode.
+
+The orange rectangle represents a scaled viewport and the area that will be visible on the screen after releasing keys. Zooming will scale that box and dragging with the middle mouse button will move everything.
+
+The black rectangle represents a canvas border. You can drag canvas using the right mouse button. Dragging canvas will add a render offset between ImGui content and the viewport.
+
+> Image(s) needed.
+
+### Properties
+
+ImGui module has a set of properties that allow to modify its behaviour:
+
+- `Input Enabled` - Whether ImGui should receive [input](#input-mode). It is possible to assign a [keyboard shortcut](#keyboard-shortcuts) to toggle this property.
+- `Keyboard Navigation`- Whether ImGui [keyboard navigation feature](#keyboard-and-gamepad-navigation) is enabled.
+- `Gamepad Navigation` - Whether ImGui [gamepad navigation feature](#keyboard-and-gamepad-navigation) is enabled.
+- `Keyboard Input Shared` - Whether keyboard input should be [shared with the game](#sharing-input). Default behaviour can be configured in [input settings](#input).
+- `Gamepad Input Shared` - Whether gamepad input should be [shared with the game](#sharing-input). Default behaviour can be configured in [input settings](#input).
+- `Mouse Input Shared` - Whether mouse input should be [shared with the game](#sharing-input). Default behaviour can be configured in [input settings](#input).
+- `Show Demo` - Whether to show ImGui demo.
+
+All properties can be changed by corresponding [console commands](#console-commands) or from code.
+
+You can get properties interface through the module instance:
+
+```C++
+FImGuiModule::Get().GetProperties();
+```
+
+### Console commands
+
+- `ImGui.ToggleInput` - Toggle ImGui input mode. It is possible to assign a [keyboard shortcut](#keyboard-shortcuts) to this command.
+- `ImGui.ToggleKeyboardNavigation` - Toggle ImGui keyboard navigation.
+- `ImGui.ToggleGamepadNavigation` - Toggle ImGui gamepad navigation.
+- `ImGui.ToggleKeyboardInputSharing` - Toggle ImGui keyboard input sharing.
+- `ImGui.ToggleGamepadInputSharing` - Toggle ImGui gamepad input sharing.
+- `ImGui.ToggleMouseInputSharing` - Toggle ImGui mouse input sharing.
+- `ImGui.ToggleDemo` - Toggle ImGui demo.
+
+### Console debug variables
+
+There is a self-debug functionality build into this plugin. This is hidden by default as it is hardly useful outside of this pluguin. To enable it, go to `ImGuiModuleDebug.h` and change `IMGUI_MODULE_DEVELOPER`.
+
+- `ImGui.Debug.Widget` - Show debug for SImGuiWidget.
+- `ImGui.Debug.Input` - Show debug for input state.
+
+### Settings
+Plugin settings can be found in *Project Settings/Plugins/ImGui* panel. There is a bunch of properties allowing to tweak input handling, keyboard shortcuts (one for now), canvas size and DPI scale.
+
+##### Extensions
+- `ImGui Input Handler Class` - Path to own implementation of ImGui Input Handler that allows limited customization of the input handling. If not set, then the default implementation is used.
+
+>*If you decide to implement an own handler, please keep in mind that I'm thinking about replacing it.*
+
+##### Input
+- `Share Keyboard Input` - Whether by default, ImGui should [share with game](#sharing-input) keyboard input.
+- `Share Gamepad Input` - Whether by default, ImGui should [share with game](#sharing-input) gamepad input.
+- `Share Mouse Input` - Whether by default, ImGui should [share with game](#sharing-input) mouse input.
+- `Use Software Cursor` - Whether ImGui should draw its own cursor in place of the hardware one.
+
+##### Keyboard shortcuts
+- `Toggle Input` - Allows to define a shortcut key to a command that toggles the input mode. Note that this is using `DebugExecBindings` which is not available in shipping builds.

+# Q&A: Basics
+
+### Q: Where is the documentation?
+
+**This library is poorly documented at the moment and expects of the user to be acquainted with C/C++.**
+- Run the examples/ and explore them.
+- See demo code in [imgui_demo.cpp](https://github.com/ocornut/imgui/blob/master/imgui_demo.cpp) and particularly the `ImGui::ShowDemoWindow()` function.
+- The demo covers most features of Dear ImGui, so you can read the code and see its output.
+- See documentation and comments at the top of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) + general API comments in [imgui.h](https://github.com/ocornut/imgui/blob/master/imgui.h).
+- Dozens of standalone example applications using e.g. OpenGL/DirectX are provided in the [examples/](https://github.com/ocornut/imgui/blob/master/examples/) folder to explain how to integrate Dear ImGui with your own engine/application.
+- Your programming IDE is your friend, find the type or function declaration to find comments associated to it.
+
+---
+
+### Q: Which version should I get?
+I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
+
+You may also peak at the [docking](https://github.com/ocornut/imgui/tree/docking) branch which includes:
+- [Docking/Merging features](https://github.com/ocornut/imgui/issues/2109)
+- [Multi-viewport features](https://github.com/ocornut/imgui/issues/1542)
+
+Many projects are using this branch and it is kept in sync with master regularly.
+
+---
+
+### Q: Why the names "Dear ImGui" vs "ImGui"?
+
+**TL;DR: Please try to refer to this library as "Dear ImGui".**
+
+The library started its life as "ImGui" due to the fact that I didn't give it a proper name when when I released 1.0, and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations (e.g. Unity uses it own implementation of the IMGUI paradigm). To reduce the ambiguity without affecting existing code bases, I have decided on an alternate, longer name "Dear ImGui" that people can use to refer to this specific library.

+
+# Q&A: Concerns
+
+### Q: Who uses Dear ImGui?
+
+You may take a look at:
+
+- [Quotes](https://github.com/ocornut/imgui/wiki/Quotes)
+- [Software using Dear ImGui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui)
+- [Gallery](https://github.com/ocornut/imgui/issues/2847)
+
+### Q: Can you create elaborate/serious tools with Dear ImGui?
+
+Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
+
+Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might require you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
+
+Dear ImGui is built to be efficient and scalable toward the needs for AAA-quality applications running all day. The IMGUI paradigm offers different opportunities for optimization that the more typical RMGUI paradigm.
+
+### Q: Can you reskin the look of Dear ImGui?
+
+Somehow. You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Dear ImGui is NOT designed to create user interface for games, although with ingenious use of the low-level API you can do it.
+
+A reasonably skinned application may look like (screenshot from [#2529](https://github.com/ocornut/imgui/issues/2529#issuecomment-524281119))
+![minipars](https://user-images.githubusercontent.com/314805/63589441-d9794f00-c5b1-11e9-8d96-cfc1b93702f7.png)
+
+### Q: Why using C++ (as opposed to C)?
+
+Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
+
+There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. It is designed for creating binding to other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for various third-party bindings.

+
+# Q&A: Integration
+
+### Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or to my application?
+
+You can read the `io.WantCaptureMouse`, `io.WantCaptureKeyboard` and `io.WantTextInput` flags from the ImGuiIO structure.
+
+e.g. `if (ImGui::GetIO().WantCaptureMouse) { ... }`
+
+- When `io.WantCaptureMouse` is set, imgui wants to use your mouse state, and you may want to discard/hide the inputs from the rest of your application.
+- When `io.WantCaptureKeyboard` is set, imgui wants to use your keyboard state, and you may want to discard/hide the inputs from the rest of your application.
+- When `io.WantTextInput` is set to may want to notify your OS to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console OS).
+
+**Note:** You should always pass your mouse/keyboard inputs to Dear ImGui, even when the io.WantCaptureXXX flag are set false.
+ This is because imgui needs to detect that you clicked in the void to unfocus its own windows.
+
+**Note:** The `io.WantCaptureMouse` is more accurate that any manual attempt to "check if the mouse is hovering a window" (don't do that!). It handle mouse dragging correctly (both dragging that started over your application or over an imgui window) and handle e.g. modal windows blocking inputs. Those flags are updated by `ImGui::NewFrame()`. Preferably read the flags after calling NewFrame() if you can afford it, but reading them before is also perfectly fine, as the bool toggle fairly rarely. If you have on a touch device, you might find use for an early call to `UpdateHoveredWindowAndCaptureFlags()`.
+
+**Note:** Text input widget releases focus on "Return KeyDown", so the subsequent "Return KeyUp" event that your application receive will typically have `io.WantCaptureKeyboard == false`. Depending on your application logic it may or not be inconvenient. You might want to track which key-downs were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)
+
+---
+
+### Q: How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display)
+- You can control Dear ImGui with a gamepad. Read about navigation in "Using gamepad/keyboard navigation controls".
+(short version: map gamepad inputs into the io.NavInputs[] array + set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).
+- You can share your computer mouse seamlessly with your console/tablet/phone using [Synergy](https://symless.com/synergy)
+This is the preferred solution for developer productivity.
+In particular, the [micro-synergy-client repository](https://github.com/symless/micro-synergy-client) has simple
+and portable source code (uSynergy.c/.h) for a small embeddable client that you can use on any platform to connect
+to your host computer, based on the Synergy 1.x protocol. Make sure you download the Synergy 1 server on your computer.
+Console SDK also sometimes provide equivalent tooling or wrapper for Synergy-like protocols.
+- You may also use a third party solution such as [Remote ImGui](https://github.com/JordiRos/remoteimgui) or [imgui-ws](https://github.com/ggerganov/imgui-ws) which sends the vertices to render over the local network, allowing you to use Dear ImGui even on a screen-less machine. See Wiki index for most details.
+- For touch inputs, you can increase the hit box of widgets (via the `style.TouchPadding` setting) to accommodate
+for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing
+for screen real-estate and precision.
+
+---
+
+### Q: I integrated Dear ImGui in my engine and the text or lines are blurry..
+In your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f).
+Also make sure your orthographic projection matrix and io.DisplaySize matches your actual framebuffer dimension.
+
+---
+
+### Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around..
+You are probably mishandling the clipping rectangles in your render function.
+Rectangles provided by ImGui are defined as
+`(x1=left,y1=top,x2=right,y2=bottom)`
+and **NOT** as
+`(x1,y1,width,height)`

+# Q&A: Usage
+
+### Q: Why are multiple widgets reacting when I interact with a single one? <br>Q: How can I have multiple widgets with the same label or with an empty label?
+
+A primer on labels and the ID Stack...
+
+Dear ImGui internally need to uniquely identify UI elements.
+Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
+Interactive widgets (such as calls to Button buttons) need a unique ID.
+Unique ID are used internally to track active widgets and occasionally associate state to widgets.
+Unique ID are implicitly built from the hash of multiple elements that identify the "path" to the UI element.
+
+- Unique ID are often derived from a string label:
+```c
+Button("OK");          // Label = "OK",     ID = hash of (..., "OK")
+Button("Cancel");      // Label = "Cancel", ID = hash of (..., "Cancel")
+```
+- ID are uniquely scoped within windows, tree nodes, etc. which all pushes to the ID stack. Having
+two buttons labeled "OK" in different windows or different tree locations is fine.
+We used "..." above to signify whatever was already pushed to the ID stack previously:
+```c
+Begin("MyWindow");
+Button("OK");          // Label = "OK",     ID = hash of ("MyWindow", "OK")
+End();
+Begin("MyOtherWindow");
+Button("OK");          // Label = "OK",     ID = hash of ("MyOtherWindow", "OK")
+End();
+```
+- If you have a same ID twice in the same location, you'll have a conflict:
+```c
+Button("OK");
+Button("OK");          // ID collision! Interacting with either button will trigger the first one.
+```
+Fear not! this is easy to solve and there are many ways to solve it!
+
+- Solving ID conflict in a simple/local context:
+When passing a label you can optionally specify extra ID information within string itself.
+Use "##" to pass a complement to the ID that won't be visible to the end-user.
+This helps solving the simple collision cases when you know e.g. at compilation time which items
+are going to be created:
+```c
+Begin("MyWindow");
+Button("Play");        // Label = "Play",   ID = hash of ("MyWindow", "Play")
+Button("Play##foo1");  // Label = "Play",   ID = hash of ("MyWindow", "Play##foo1")  // Different from above
+Button("Play##foo2");  // Label = "Play",   ID = hash of ("MyWindow", "Play##foo2")  // Different from above
+End();
+```
+- If you want to completely hide the label, but still need an ID:
+```c
+Checkbox("##On", &b);  // Label = "",       ID = hash of (..., "##On")   // No visible label, just a checkbox!
+```
+- Occasionally/rarely you might want change a label while preserving a constant ID. This allows
+you to animate labels. For example you may want to include varying information in a window title bar,
+but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID:
+```c
+Button("Hello###ID");  // Label = "Hello",  ID = hash of (..., "###ID")
+Button("World###ID");  // Label = "World",  ID = hash of (..., "###ID")  // Same as above, even if the label looks different
+
+sprintf(buf, "My game (%f FPS)###MyGame", fps);
+Begin(buf);            // Variable title,   ID = hash of "MyGame"
+```
+- Solving ID conflict in a more general manner:
+Use PushID() / PopID() to create scopes and manipulate the ID stack, as to avoid ID conflicts
+within the same window. This is the most convenient way of distinguishing ID when iterating and
+creating many UI elements programmatically.
+You can push a pointer, a string or an integer value into the ID stack.
+Remember that ID are formed from the concatenation of _everything_ pushed into the ID stack.
+At each level of the stack we store the seed used for items at this level of the ID stack.
+```c
+Begin("Window");
+for (int i = 0; i < 100; i++)
+{
+  PushID(i);           // Push i to the id tack
+  Button("Click");     // Label = "Click",  ID = hash of ("Window", i, "Click")
+  PopID();
+}
+for (int i = 0; i < 100; i++)
+{
+  MyObject* obj = Objects[i];
+  PushID(obj);
+  Button("Click");     // Label = "Click",  ID = hash of ("Window", obj pointer, "Click")
+  PopID();
+}
+for (int i = 0; i < 100; i++)
+{
+  MyObject* obj = Objects[i];
+  PushID(obj->Name);
+  Button("Click");     // Label = "Click",  ID = hash of ("Window", obj->Name, "Click")
+  PopID();
+}
+End();
+```
+- You can stack multiple prefixes into the ID stack:
+```c
+Button("Click");       // Label = "Click",  ID = hash of (..., "Click")
+PushID("node");
+  Button("Click");     // Label = "Click",  ID = hash of (..., "node", "Click")
+  PushID(my_ptr);
+    Button("Click");   // Label = "Click",  ID = hash of (..., "node", my_ptr, "Click")
+  PopID();
+PopID();
+```
+- Tree nodes implicitly creates a scope for you by calling PushID().
+```c
+Button("Click");       // Label = "Click",  ID = hash of (..., "Click")
+if (TreeNode("node"))  // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag)
+{
+  Button("Click");     // Label = "Click",  ID = hash of (..., "node", "Click")
+  TreePop();
+}
+```
+- When working with trees, ID are used to preserve the open/close state of each tree node.
+Depending on your use cases you may want to use strings, indices or pointers as ID.
+e.g. when following a single pointer that may change over time, using a static string as ID
+will preserve your node open/closed state when the targeted object change.
+e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
+node open/closed state differently. See what makes more sense in your situation!

+
+### Q: How can I display an image? What is ImTextureID, how does it work?
+
+Short explanation:
+- Please read Wiki entry for examples: https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples
+- You may use functions such as `ImGui::Image()`, `ImGui::ImageButton()` or lower-level `ImDrawList::AddImage()` to emit draw calls that will use your own textures.
+- Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value.
+- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason).
+
+**Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward.**
+
+Long explanation:
+- Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder we provide functions for popular graphics API (OpenGL, DirectX, etc.).
+- Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
+ We carry the information to identify a "texture" in the ImTextureID type.
+ImTextureID is nothing more that a void*, aka 4/8 bytes worth of data: just enough to store 1 pointer or 1 integer of your choice.
+Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely pass ImTextureID values until they reach your rendering function.
+- In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) bindings, for each graphics API binding we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
+```
+OpenGL:
+- ImTextureID = GLuint
+- See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp
+
+DirectX9:
+- ImTextureID = LPDIRECT3DTEXTURE9
+- See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp
+
+DirectX11:
+- ImTextureID = ID3D11ShaderResourceView*
+- See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp
+
+DirectX12:
+- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE
+- See ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp
+```
+For example, in the OpenGL example binding we store raw OpenGL texture identifier (GLuint) inside ImTextureID.
+Whereas in the DirectX11 example binding we store a pointer to ID3D11ShaderResourceView inside ImTextureID, which is a higher-level structure tying together both the texture and information about its format and how to read it.
+
+- If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better knowing how your codebase is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them.
+If you are starting with OpenGL or DirectX or Vulkan and haven't built much of a rendering engine over them, keeping the default ImTextureID representation suggested by the example bindings is probably the best choice.
+(Advanced users may also decide to keep a low-level type in ImTextureID, and use ImDrawList callback and pass information to their renderer)
+
+User code may do:
+```cpp
+// Cast our texture type to ImTextureID / void*
+MyTexture* texture = g_CoffeeTableTexture;
+ImGui::Image((void*)texture, ImVec2(texture->Width, texture->Height));
+```
+The renderer function called after ImGui::Render() will receive that same value that the user code passed:
+```cpp
+// Cast ImTextureID / void* stored in the draw command as our texture type
+MyTexture* texture = (MyTexture*)pcmd->TextureId;
+MyEngineBindTexture2D(texture);
+```
+Once you understand this design you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui.
+This is by design and is actually a good thing, because it means your code has full control over your data types and how you display them.
+If you want to display an image file (e.g. PNG file) into the screen, please refer to documentation and tutorials for the graphics API you are using.
+
+Refer to the Wiki to find simplified examples for loading textures with OpenGL, DirectX9 and DirectX11: https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples
+
+C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa.
+Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*.
+Examples:
+```cpp
+GLuint my_tex = XXX;
+void* my_void_ptr;
+my_void_ptr = (void*)(intptr_t)my_tex;                  // cast a GLuint into a void* (we don't take its address! we literally store the value inside the pointer)
+my_tex = (GLuint)(intptr_t)my_void_ptr;                 // cast a void* into a GLuint
+
+ID3D11ShaderResourceView* my_dx11_srv = XXX;
+void* my_void_ptr;
+my_void_ptr = (void*)my_dx11_srv;                       // cast a ID3D11ShaderResourceView* into an opaque void*
+my_dx11_srv = (ID3D11ShaderResourceView*)my_void_ptr;   // cast a void* into a ID3D11ShaderResourceView*
+```
+Finally, you may call ImGui::ShowMetricsWindow() to explore/visualize/understand how the ImDrawList are generated.
+
+---
+
+### Q: How can I use my own math types instead of ImVec2/ImVec4?
+
+You can edit [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) and setup the IM_VEC2_CLASS_EXTRA/IM_VEC4_CLASS_EXTRA macros to add implicit type conversions.
+This way you'll be able to use your own types everywhere, e.g. passing MyVector2 or glm::vec2 to ImGui functions instead of ImVec2.
+
+---
+
+### Q: How can I interact with standard C++ types (such as std::string and std::vector)?
+- Being highly portable (bindings for several languages, frameworks, programming style, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engines, dear imgui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases.
+- To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h).
+- To use combo boxes and list boxes with std::vector or any other data structure: the BeginCombo()/EndCombo() API
+lets you iterate and submit items yourself, so does the ListBoxHeader()/ListBoxFooter() API.
+Prefer using them over the old and awkward Combo()/ListBox() api.
+- Generally for most high-level types you should be able to access the underlying data type.
+You may write your own one-liner wrappers to facilitate user code (tip: add new functions in ImGui:: namespace from your code).
+- Dear ImGui applications often need to make intensive use of strings. It is expected that many of the strings you will pass
+to the API are raw literals (free in C/C++) or allocated in a manner that won't incur a large cost on your application.
+Please bear in mind that using std::string on applications with large amount of UI may incur unsatisfactory performances.
+Modern implementations of std::string often include small-string optimization (which is often a local buffer) but those
+are not configurable and not the same across implementations.
+- If you are finding your UI traversal cost to be too large, make sure your string usage is not leading to excessive amount
+of heap allocations. Consider using literals, statically sized buffers and your own helper functions. A common pattern
+is that you will need to build lots of strings on the fly, and their maximum length can be easily be scoped ahead.
+One possible implementation of a helper to facilitate printf-style building of strings: https://github.com/ocornut/Str
+This is a small helper where you can instance strings with configurable local buffers length. Many game engines will
+provide similar or better string helpers.
+
+---
+
+### Q: How can I display custom shapes? (using low-level ImDrawList API)
+
+- You can use the low-level `ImDrawList` api to render shapes within a window.
+
+```
+ImGui::Begin("My shapes");
+
+ImDrawList* draw_list = ImGui::GetWindowDrawList();
+
+// Get the current ImGui cursor position
+ImVec2 p = ImGui::GetCursorScreenPos();
+
+// Draw a red circle
+draw_list->AddCircleFilled(ImVec2(p.x + 50, p.y + 50), 30.0f, IM_COL32(255, 0, 0, 255), 16);
+
+// Draw a 3 pixel thick yellow line
+draw_list->AddLine(ImVec2(p.x, p.y), ImVec2(p.x + 100.0f, p.y + 100.0f), IM_COL32(255, 255, 0, 255), 3.0f);
+
+// Advance the ImGui cursor to claim space in the window (otherwise the window will appears small and needs to be resized)
+ImGui::Dummy(ImVec2(200, 200));
+
+ImGui::End();
+```
+![ImDrawList usage](https://raw.githubusercontent.com/wiki/ocornut/imgui/tutorials/CustomRendering01.png)
+
+- Refer to "Demo > Examples > Custom Rendering" in the demo window and read the code of `ShowExampleAppCustomRendering()` in `imgui_demo.cpp` from more examples.
+- To generate colors: you can use the macro `IM_COL32(255,255,255,255)` to generate them at compile time, or use `ImGui::GetColorU32(IM_COL32(255,255,255,255))` or `ImGui::GetColorU32(ImVec4(1.0f,1.0f,1.0f,1.0f))` to generate a color that is multiplied by the current value of `style.Alpha`.
+- Math operators: if you have setup `IM_VEC2_CLASS_EXTRA` in `imconfig.h` to bind your own math types, you can use your own math types and their natural operators instead of ImVec2. ImVec2 by default doesn't export any math operators in the public API. You may use `#define IMGUI_DEFINE_MATH_OPERATORS` `#include "imgui_internal.h"` to use the internally defined math operators, but instead prefer using your own math library and set it up in `imconfig.h`.
+- You can use `ImGui::GetBackgroundDrawList()` or `ImGui::GetForegroundDrawList()` to access draw lists which will be displayed behind and over every other dear imgui windows (one bg/fg drawlist per viewport). This is very convenient if you need to quickly display something on the screen that is not associated to a dear imgui window.
+- You can also create your own dummy window and draw inside it. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags (The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse). Then you can retrieve the ImDrawList* via GetWindowDrawList() and draw to it in any way you like.
+- You can create your own ImDrawList instance. You'll need to initialize them with `ImGui::GetDrawListSharedData()`, or create your own instancing ImDrawListSharedData, and then call your renderer function with your own ImDrawList or ImDrawData data.

+# Q&A: Fonts, Text
+
+### Q: How can I load a different font than the default?
+Use the font atlas to load the TTF/OTF file you want:
+
+```c
+ImGuiIO& io = ImGui::GetIO();
+io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
+io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+```
+
+Default is ProggyClean.ttf, monospace, rendered at size 13, embedded in dear imgui's source code.
+
+(Tip: monospace fonts are convenient because they allow to facilitate horizontal alignment directly at the string level.)
+
+(Read the [docs/FONTS.txt](https://github.com/ocornut/imgui/blob/master/docs/FONTS.txt) file for more details about font loading.)
+
+New programmers: remember that in C/C++ and most programming languages if you want to use a
+backslash \ within a string literal, you need to write it double backslash "\\":
+
+```c
+io.Fonts->AddFontFromFileTTF("MyFolder\MyFont.ttf", size);  // WRONG (you are escape the M here!)
+io.Fonts->AddFontFromFileTTF("MyFolder\\MyFont.ttf", size;  // CORRECT
+io.Fonts->AddFontFromFileTTF("MyFolder/MyFont.ttf", size);  // ALSO CORRECT
+```
+
+---
+
+### Q: How can I easily use icons in my application?
+The most convenient and practical way is to merge an icon font such as FontAwesome inside you
+main font. Then you can refer to icons within your strings.
+You may want to see ImFontConfig::GlyphMinAdvanceX to make your icon look monospace to facilitate alignment.
+(Read the [docs/FONTS.txt](https://github.com/ocornut/imgui/blob/master/docs/FONTS.txt) file for more details about icons font loading.)
+With some extra effort, you may use colorful icon by registering custom rectangle space inside the font atlas,
+and copying your own graphics data into it. See docs/FONTS.txt about using the AddCustomRectFontGlyph API.
+
+---
+
+### Q: How can I load multiple fonts?
+Use the font atlas to pack them into a single texture:
+(Read the [docs/FONTS.txt](https://github.com/ocornut/imgui/blob/master/docs/FONTS.txt) file and the code in ImFontAtlas for more details.)
+
+```cpp
+ImGuiIO& io = ImGui::GetIO();
+ImFont* font0 = io.Fonts->AddFontDefault();
+ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
+ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);
+io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
+// the first loaded font gets used by default
+// use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
+
+// Options
+ImFontConfig config;
+config.OversampleH = 2;
+config.OversampleV = 1;
+config.GlyphOffset.y -= 1.0f;      // Move everything by 1 pixels up
+config.GlyphExtraSpacing.x = 1.0f; // Increase spacing between characters
+io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels, &config);
+
+// Combine multiple fonts into one (e.g. for icon fonts)
+static ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
+ImFontConfig config;
+config.MergeMode = true;
+io.Fonts->AddFontDefault();
+io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); // Merge icon font
+io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels, NULL, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge japanese glyphs
+```
+
+---
+
+### Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
+When loading a font, pass custom Unicode ranges to specify the glyphs to load.
+
+```cpp
+// Add default Japanese ranges
+io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
+
+// Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
+ImVector<ImWchar> ranges;
+ImFontGlyphRangesBuilder builder;
+builder.AddText("Hello world");                        // Add a string (here "Hello world" contains 7 unique characters)
+builder.AddChar(0x7262);                               // Add a specific character
+builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
+builder.BuildRanges(&ranges);                          // Build the final result (ordered ranges with all the unique characters submitted)
+io.Fonts->AddFontFromFileTTF("myfontfile.ttf", 16.0f, NULL, ranges.Data);
+```
+
+All your strings needs to use UTF-8 encoding. In C++11 you can encode a string literal in UTF-8
+by using the u8"hello" syntax. Specifying literal in your source code using a local code page
+(such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
+Otherwise you can convert yourself to UTF-8 or load text data from file already saved as UTF-8.
+
+Text input: it is up to your application to pass the right character code by calling io.AddInputCharacter().
+The applications in examples/ are doing that.
+Windows: you can use the WM_CHAR or WM_UNICHAR or WM_IME_CHAR message (depending if your app is built using Unicode or MultiByte mode).
+You may also use MultiByteToWideChar() or ToUnicode() to retrieve Unicode codepoints from MultiByte characters or keyboard state.
+Windows: if your language is relying on an Input Method Editor (IME), you copy the HWND of your window to io.ImeWindowHandle in order for
+the default implementation of io.ImeSetInputScreenPosFn() to set your Microsoft IME position correctly.

+# Q&A: Community
+
+### Q: How can I help?
+- If you are experienced with Dear ImGui and C++, look at the [GitHub Issues](https://github.com/ocornut/imgui/issues), look at the [Wiki](https://github.com/ocornut/imgui/wiki), read [docs/TODO.txt](https://github.com/ocornut/imgui/blob/master/docs/TODO.txt) and see how you want to help and can help!
+- Businesses: convince your company to fund development via support contracts/sponsoring! This is among the most useful thing you can do for Dear ImGui. With increased funding we will be able to hire more people working on this project.
+- Individuals: you can also become a [Patron](http://www.patreon.com/imgui) or donate on PayPal! See README.
+- Disclose your usage of dear imgui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
+You may post screenshot or links in the [gallery threads](https://github.com/ocornut/imgui/issues/2847). Visuals are ideal as they inspire other programmers.
+But even without visuals, disclosing your use of dear imgui help the library grow credibility, and help other teams and programmers with taking decisions.
+- If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues or sometimes incomplete pR.

+FONTS DOCUMENTATION
+
+Also read https://www.dearimgui.org/faq for more fonts related infos.
+
+The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer),
+a 13 pixels high, pixel-perfect font used by default.
+We embed it font in source code so you can use Dear ImGui without any file system access.
+
+You may also load external .TTF/.OTF files.
+The files in this folder are suggested fonts, provided as a convenience.
+
+Please read the FAQ: https://www.dearimgui.org/faq
+Please use the Discord server: http://discord.dearimgui.org and not the Github issue tracker for basic font loading questions.

+ README FIRST / FAQ
+---------------------------------------
+
+- You can use the style editor ImGui::ShowStyleEditor() in the "Fonts" section to browse your fonts
+  and understand what's going on if you have an issue.
+- Fonts are rasterized in a single texture at the time of calling either of io.Fonts->GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build().
+- Make sure your font ranges data are persistent and available at the time the font atlas is being built.
+- Use C++11 u8"my text" syntax to encode literal strings as UTF-8. e.g.:
+      u8"hello"
+      u8"こんにちは"   // this will be encoded as UTF-8
+- If you want to include a backslash \ character in your string literal, you need to double them e.g. "folder\\filename".
+  Read FAQ for details.

+---------------------------------------
+ FONTS LOADING INSTRUCTIONS
+---------------------------------------
+
+Load default font:
+
+  ImGuiIO& io = ImGui::GetIO();
+  io.Fonts->AddFontDefault();
+
+Load .TTF/.OTF file with:
+
+  ImGuiIO& io = ImGui::GetIO();
+  io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+
+Load multiple fonts:
+
+  ImGuiIO& io = ImGui::GetIO();
+  ImFont* font1 = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+  ImFont* font2 = io.Fonts->AddFontFromFileTTF("anotherfont.otf", size_pixels);
+
+  // Select font at runtime
+  ImGui::Text("Hello");	// use the default font (which is the first loaded font)
+  ImGui::PushFont(font2);
+  ImGui::Text("Hello with another font");
+  ImGui::PopFont();
+
+For advanced options create a ImFontConfig structure and pass it to the AddFont function (it will be copied internally):
+
+  ImFontConfig config;
+  config.OversampleH = 2;
+  config.OversampleV = 1;
+  config.GlyphExtraSpacing.x = 1.0f;
+  ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
+
+Combine two fonts into one:
+
+  // Load a first font
+  ImFont* font = io.Fonts->AddFontDefault();
+
+  // Add character ranges and merge into the previous font
+  // The ranges array is not copied by the AddFont* functions and is used lazily
+  // so ensure it is available at the time of building or calling GetTexDataAsRGBA32().
+  static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // Will not be copied by AddFont* so keep in scope.
+  ImFontConfig config;
+  config.MergeMode = true;
+  io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese());
+  io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges);
+  io.Fonts->Build();
+
+Font atlas is too large?
+
+- If you have very large number of glyphs or multiple fonts, the texture may become too big for your graphics API.
+- The typical result of failing to upload a texture is if every glyphs appears as white rectangles.
+- In particular, using a large range such as GetGlyphRangesChineseSimplifiedCommon() is not recommended
+  unless you set OversampleH/OversampleV to 1 and use a small font size.
+- Mind the fact that some graphics drivers have texture size limitation.
+- If you are building a PC application, mind the fact that users may run on hardware with lower specs than yours.
+
+Some solutions:
+
+ - 1) Reduce glyphs ranges by calculating them from source localization data.
+   You can use ImFontGlyphRangesBuilder for this purpose, this will be the biggest win!
+ - 2) You may reduce oversampling, e.g. config.OversampleH = config.OversampleV = 1, this will largely reduce your texture size.
+ - 3) Set io.Fonts.TexDesiredWidth to specify a texture width to minimize texture height (see comment in ImFontAtlas::Build function).
+ - 4) Set io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight; to disable rounding the texture height to the next power of two.
+ - Read about oversampling here: https://github.com/nothings/stb/blob/master/tests/oversample
+
+
+Add a fourth parameter to bake specific font ranges only:
+
+  // Basic Latin, Extended Latin
+  io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesDefault());
+
+  // Default + Selection of 2500 Ideographs used by Simplified Chinese
+  io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());
+
+  // Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
+  io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
+
+See "BUILDING CUSTOM GLYPH RANGES" section to create your own ranges.
+Offset font vertically by altering the io.Font->DisplayOffset value:
+
+  ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+  font->DisplayOffset.y = 1;   // Render 1 pixel down
+
+
+---------------------------------------
+ USING ICONS
+---------------------------------------
+
+Using an icon font (such as FontAwesome: http://fontawesome.io or OpenFontIcons. https://github.com/traverseda/OpenFontIcons)
+is an easy and practical way to use icons in your Dear ImGui application.
+A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without
+having to change fonts back and forth.
+
+To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut:
+
+  https://github.com/juliettef/IconFontCppHeaders
+
+Those files contains a bunch of named #define which you can use to refer to specific icons of the font, e.g.:
+
+  #define ICON_FA_MUSIC   "\xef\x80\x81"
+  #define ICON_FA_SEARCH  "\xef\x80\x82"
+
+Example Setup:
+
+  // Merge icons into default tool font
+  #include "IconsFontAwesome.h"
+  ImGuiIO& io = ImGui::GetIO();
+  io.Fonts->AddFontDefault();
+
+  ImFontConfig config;
+  config.MergeMode = true;
+  config.GlyphMinAdvanceX = 13.0f; // Use if you want to make the icon monospaced
+  static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
+  io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
+
+Example Usage:
+
+  // Usage, e.g.
+  ImGui::Text("%s among %d items", ICON_FA_SEARCH, count);
+  ImGui::Button(ICON_FA_SEARCH " Search");
+
+Important to understand: C string _literals_ can be concatenated at compilation time, e.g. "hello" " world"
+ICON_FA_SEARCH is defined as a string literal so this is the same as "A" "B" becoming "AB"
+
+See Links below for other icons fonts and related tools.
+
+
+---------------------------------------
+ FREETYPE RASTERIZER, SMALL FONT SIZES
+---------------------------------------
+
+Dear ImGui uses imstb_truetype.h to rasterize fonts (with optional oversampling).
+This technique and its implementation are not ideal for fonts rendered at _small sizes_, which may appear a
+little blurry or hard to read.
+
+There is an implementation of the ImFontAtlas builder using FreeType that you can use in the misc/freetype/ folder.
+
+FreeType supports auto-hinting which tends to improve the readability of small fonts.
+Note that this code currently creates textures that are unoptimally too large (could be fixed with some work).
+Also note that correct sRGB space blending will have an important effect on your font rendering quality.
+
+
+---------------------------------------
+ BUILDING CUSTOM GLYPH RANGES
+---------------------------------------
+
+You can use the ImFontGlyphRangesBuilder helper to create glyph ranges based on text input.
+For example: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
+
+  ImVector<ImWchar> ranges;
+  ImFontGlyphRangesBuilder builder;
+  builder.AddText("Hello world");                        // Add a string (here "Hello world" contains 7 unique characters)
+  builder.AddChar(0x7262);                               // Add a specific character
+  builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
+  builder.BuildRanges(&ranges);                          // Build the final result (ordered ranges with all the unique characters submitted)
+
+  io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, NULL, ranges.Data);
+  io.Fonts->Build();                                     // Build the atlas while 'ranges' is still in scope and not deleted.
+
+
+---------------------------------------
+ USING CUSTOM COLORFUL ICONS
+---------------------------------------
+
+(This is a BETA api, use if you are familiar with dear imgui and with your rendering back-end)
+
+You can use the ImFontAtlas::AddCustomRect() and ImFontAtlas::AddCustomRectFontGlyph() api to register rectangles
+that will be packed into the font atlas texture. Register them before building the atlas, then call Build().
+You can then use ImFontAtlas::GetCustomRectByIndex(int) to query the position/size of your rectangle within the
+texture, and blit/copy any graphics data of your choice into those rectangles.
+
+Pseudo-code:
+
+  // Add font, then register two custom 13x13 rectangles mapped to glyph 'a' and 'b' of this font
+  ImFont* font = io.Fonts->AddFontDefault();
+  int rect_ids[2];
+  rect_ids[0] = io.Fonts->AddCustomRectFontGlyph(font, 'a', 13, 13, 13+1);
+  rect_ids[1] = io.Fonts->AddCustomRectFontGlyph(font, 'b', 13, 13, 13+1);
+
+  // Build atlas
+  io.Fonts->Build();
+
+  // Retrieve texture in RGBA format
+  unsigned char* tex_pixels = NULL;
+  int tex_width, tex_height;
+  io.Fonts->GetTexDataAsRGBA32(&tex_pixels, &tex_width, &tex_height);
+
+  for (int rect_n = 0; rect_n < IM_ARRAYSIZE(rect_ids); rect_n++)
+  {
+      int rect_id = rects_ids[rect_n];
+      if (const ImFontAtlas::CustomRect* rect = io.Fonts->GetCustomRectByIndex(rect_id))
+      {
+          // Fill the custom rectangle with red pixels (in reality you would draw/copy your bitmap data here!)
+          for (int y = 0; y < rect->Height; y++)
+          {
+              ImU32* p = (ImU32*)tex_pixels + (rect->Y + y) * tex_width + (rect->X);
+              for (int x = rect->Width; x > 0; x--)
+                  *p++ = IM_COL32(255, 0, 0, 255);
+          }
+      }
+  }
+
+
+---------------------------------------
+ EMBEDDING FONTS IN SOURCE CODE
+---------------------------------------
+
+Compile and use 'binary_to_compressed_c.cpp' to create a compressed C style array that you can embed in source code.
+See the documentation in binary_to_compressed_c.cpp for instruction on how to use the tool.
+You may find a precompiled version binary_to_compressed_c.exe for Windows instead of demo binaries package (see README).
+The tool can optionally output Base85 encoding to reduce the size of _source code_ but the read-only arrays in the
+actual binary will be about 20% bigger.
+
+Then load the font with:
+  ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
+or:
+  ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);

+
+----
+
+Dear ImGui is a **bloat-free graphical user interface library for C++**. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).
+
+Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and lacks certain features normally found in more high-level libraries.
+
+Dear ImGui is particularly suited to integration in games engine (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on consoles platforms where operating system features are non-standard.

+
+### Usage
+
+**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily copy and compile into your application/engine. They are all the files in the root folder of the repository (imgui.cpp, imgui.h, imgui_demo.cpp, imgui_draw.cpp etc.).
+
+**No specific build process is required**. You can add the .cpp files to your existing project.
+
+You will need a backend to integrate Dear ImGui in your app. The backend passes mouse/keyboard/gamepad inputs and variety of settings to Dear ImGui, and is in charge of rendering the resulting vertices.
+
+**Backends for a variety of graphics api and rendering platforms** are provided in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder, along with example applications. See the [Integration](#integration) section of this document for details. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.
+
+After Dear ImGui is setup in your application, you can use it from \_anywhere\_ in your program loop:
+
+Code:
+```cp
+ImGui::Text("Hello, world %d", 123);
+if (ImGui::Button("Save"))
+    MySaveFunction();
+ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
+ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
+```
+Result:
+<br>![sample code output](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v160/code_sample_02.png)
+<br>_(settings: Dark style (left), Light style (right) / Font: Roboto-Medium, 16px / Rounding: 5)_
+
+Code:
+```cpp
+// Create a window called "My First Tool", with a menu bar.
+ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
+if (ImGui::BeginMenuBar())
+{
+    if (ImGui::BeginMenu("File"))
+    {
+        if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
+        if (ImGui::MenuItem("Save", "Ctrl+S"))   { /* Do stuff */ }
+        if (ImGui::MenuItem("Close", "Ctrl+W"))  { my_tool_active = false; }
+        ImGui::EndMenu();
+    }
+    ImGui::EndMenuBar();
+}
+
+// Edit a color (stored as ~4 floats)
+ImGui::ColorEdit4("Color", my_color);
+
+// Plot some values
+const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f };
+ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values));
+
+// Display contents in a scrolling region
+ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
+ImGui::BeginChild("Scrolling");
+for (int n = 0; n < 50; n++)
+    ImGui::Text("%04d: Some text", n);
+ImGui::EndChild();
+ImGui::End();
+```
+Result:

+
+Dear ImGui allows you **create elaborate tools** as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc.
+
+### How it works
+
+Check out the Wiki's [About the IMGUI paradigm](https://github.com/ocornut/imgui/wiki#About-the-IMGUI-paradigm) section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize superfluous state duplication, state synchronization and state retention from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces.
+
+Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions  anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase.
+
+_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
+
+### Demo
+
+Calling the `ImGui::ShowDemoWindow()` function will create a demo window showcasing variety of features and examples. The code is always available for reference in `imgui_demo.cpp`.

+The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your style with `style.ScaleAllSizes()`.
+
+### Integration
+
+On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/examples) files without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more of the imgui_impl_xxxx files instead of rewriting them: this will be less work for you and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom binding using your custom engine functions if you wish so.
+
+Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you less than two hours to integrate Dear ImGui in your custom engine. **Make sure to spend time reading the [FAQ](https://www.dearimgui.org/faq), comments, and some of the examples/ application!**

+
+Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com) (Vita).
+
+I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it.

+ISSUES & TODO LIST
+
+Issue numbers (#) refer to github issues listed at https://github.com/ocornut/imgui/issues/XXXX
+The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
+It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
+
+ - doc/test: add a proper documentation+regression testing system (#435)
+ - doc/test: checklist app to verify binding/integration of imgui (test inputs, rendering, callback, etc.).
+ - doc/tips: tips of the day: website? applet in imgui_club?
+
+ - window: preserve/restore relative focus ordering (persistent or not) (#2304) -> also see docking reference to same #.
+ - window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
+ - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
+ - window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
+ - window: allow resizing of child windows (possibly given min/max for each axis?.)
+ - window: background options for child windows, border option (disable rounding).
+ - window: begin with *p_open == false could return false.
+ - window: get size/pos helpers given names (see discussion in #249)
+ - window: a collapsed window can be stuck behind the main menu bar?
+ - window: when window is very small, prioritize resize button over close button.
+ - window: detect extra End() call that pop the "Debug" window out and assert at End() call site instead of at end of frame.
+ - window: increase minimum size of a window with menus or fix the menu rendering so that it doesn't look odd.
+ - window: double-clicking on title bar to minimize isn't consistent, perhaps move to single-click on left-most collapse icon?
+ - window: expose contents size. (#1045)
+ - window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
+ - window: GetWindowSize() returns (0,0) when not calculated? (#1045)
+ - window: investigate better auto-positioning for new windows.
+ - window: top most window flag? (#2574)
+ - window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. -> this may require enforcing that it is illegal to submit contents if Begin returns false.
+ - window/child: the first draw command of a child window could be moved into the current draw command of the parent window (unless child+tooltip?).
+ - window/child: border could be emitted in parent as well.
+ - window/child: allow SetNextWindowContentSize() to work on child windows.
+ - window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
+ - window/tab: add a way to signify that a window or docked window requires attention (e.g. blinking title bar).
+ ! scrolling: exposing horizontal scrolling with Shift+Wheel even when scrollbar is disabled expose lots of issues (#2424, #1463)
+ - scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse)
+ - scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
+ - scrolling/clipping: separator on the initial position of a window is not visible (cursorpos.y <= clippos.y). (2017-08-20: can't repro)
+ - scrolling/style: shadows on scrollable areas to denote that there is more contents
+
+ - drawdata: make it easy to clone (or swap?) a full ImDrawData so user can easily save that data if they use threaded rendering. (e.g. #2646)
+ ! drawlist: add calctextsize func to facilitate consistent code from user pov (currently need to use ImGui or ImFont alternatives!)
+ - drawlist: end-user probably can't call Clear() directly because we expect a texture to be pushed in the stack.
+ - drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command).
+ - drawlist: primitives/helpers to manipulate vertices post submission, so e.g. a quad/rect can be resized to fit later submitted content, _without_ using the ChannelSplit api
+ - drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
+ - drawlist: non-AA strokes have gaps between points (#593, #288), glitch especially on RenderCheckmark() and ColorPicker4().
+ - drawlist: would be good to be able to deep copy of ImDrawData (we have a deep copy of ImDrawList now).
+ - drawlist: rendering: provide a way for imgui to output to a single/global vertex buffer, re-order indices only at the end of the frame (ref: https://gist.github.com/floooh/10388a0afbe08fce9e617d8aefa7d302)
+ - drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API).
+ - drawlist: AddRect vs AddLine position confusing (#2441)
+ - drawlist: channel splitter should be external helper and not stored in ImDrawList.
+ - drawlist/opt: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. (#1962)
+ - drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
+ - drawlist/opt: thick AA line could be doable in same number of triangles as 1.0 AA line by storing gradient+full color in atlas.
+
+ - main: find a way to preserve relative orders of multiple reappearing windows (so an app toggling between "modes" e.g. fullscreen vs all tools) won't lose relative ordering.
+ - main: IsItemHovered() make it more consistent for various type of widgets, widgets with multiple components, etc. also effectively IsHovered() region sometimes differs from hot region, e.g tree nodes
+ - main: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
+ - main: rename the main "Debug" window to avoid ID collision with user who may want to use "Debug" with specific flags.
+
+ - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
+ - widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
+ - widgets: add visuals for Disabled/ReadOnly mode and expose publicly (#211)
+ - widgets: add always-allow-overlap mode. This should perhaps be the default? one problem is that highlight after mouse-wheel scrolling gets deferred, makes scrolling more flickery.
+ - widgets: start exposing PushItemFlag() and ImGuiItemFlags
+ - widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
+ - widgets: activate by identifier (trigger button, focus given id)
+ - widgets: a way to represent "mixed" values, so e.g. all values replaced with *, including check-boxes, colors, etc. with support for multi-components widgets (e.g. SliderFloat3, make only "Y" mixed) (#2644)
+ - widgets: selectable: generic BeginSelectable()/EndSelectable() mechanism.
+ - widgets: selectable: a way to visualize partial/mixed selection (e.g. parent tree node has children with mixed selection)
+ - widgets: checkbox: checkbox with custom glyph inside frame.
+ - widgets: coloredit: keep reporting as active when picker is on?
+ - widgets: group/scalarn functions: expose more per-component information. e.g. store NextItemData.ComponentIdx set by scalarn function, groups can expose them back somehow.
+
+ - input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile.
+ - input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
+ - input text: expose CursorPos in char filter event (#816)
+ - input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return NULL if not active.
+ - input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
+ - input text: hover tooltip could show unclamped text
+ - input text: option to Tab after an Enter validation.
+ - input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
+ - input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
+ - input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
+ - input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it.
+ - input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
+ - input text: decorrelate layout from inputs - e.g. what's the easiest way to implement a nice IP/Mac address input editor?
+ - input text: global callback system so user can plug in an expression evaluator easily. (#1691)
+ - input text: force scroll to end or scroll to a given line/contents (so user can implement a log or a search feature)
+ - input text: a way to preview completion (e.g. disabled text completing from the cursor)
+ - input text: a side bar that could e.g. preview where errors are. probably left to the user to draw but we'd need to give them the info there.
+ - input text: a way for the user to provide syntax coloring.
+ - input text: Shift+TAB with ImGuiInputTextFlags_AllowTabInput could eat preceding blanks, up to tab_count.
+ - input text: facilitate patterns like if (InputText(..., obj.get_string_ref()) { obj.set_string(...); } relying on internally held buffer.
+ - input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
+ - input text multi-line: support for cut/paste without selection (cut/paste the current line)
+ - input text multi-line: line numbers? status bar? (follow up on #200)
+ - input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
+ - input text multi-line: better horizontal scrolling support (#383, #1224)
+ - input text multi-line: single call to AddText() should be coarse clipped on InputTextEx() end.
+ - input number: optional range min/max for Input*() functions
+ - input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
+ - input number: use mouse wheel to step up/down
+ - input number: applying arithmetics ops (+,-,*,/) messes up with text edit undo stack.
+
+ - layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
+ - layout: generalization of the above: a concept equivalent to word processor ruler tab stop ~ mini columns (position in X, no clipping implied) (vaguely relate to #267, #395, also what is used internally for menu items)
+ - layout: horizontal layout helper (#97)
+ - layout: horizontal flow until no space left (#404)
+ - layout: more generic alignment state (left/right/centered) for single items?
+ - layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
+ - layout: vertical alignment of mixed height items (e.g. buttons) within a same line (#1284)
+ - layout: null layout mode were items are not rendered but user can query GetItemRectMin()/Max/Size.
+ - layout: (R&D) local multi-pass layout mode.
+ - layout: (R&D) bind authored layout data (created by an off-line tool), items fetch their pos/size at submission, self-optimize data structures to stable linear access.
+
+ - group: BeginGroup() needs a border option. (~#1496)
+ - group: IsHovered() after EndGroup() covers whole aabb rather than the intersection of individual items. Is that desirable?
+ - group: merge deactivation/activation within same group (fwd WasEdited flag). (#2550)
+
+ - columns: sizing policy (e.g. for each column: fixed size, %, fill, distribute default size among fills) (#513, #125)
+ - columns: add a conditional parameter to SetColumnOffset() (#513, #125)
+ - columns: headers. re-orderable. (#513, #125)
+ - columns: optional sorting modifiers (up/down), sort list so sorting can be done multi-criteria. notify user when sort order changed.
+ - columns: option to alternate background colors on odd/even scanlines.
+ - columns: allow columns to recurse.
+ - columns: allow a same columns set to be interrupted by e.g. CollapsingHeader and resume with columns in sync when moving them.
+ - columns: sizing is lossy when columns width is very small (default width may turn negative etc.)
+ - columns: separator function or parameter that works within the column (currently Separator() bypass all columns) (#125)
+ - columns: flag to add horizontal separator above/below?
+ - columns/layout: setup minimum line height (equivalent of automatically calling AlignFirstTextHeightToWidgets)
+
+!- color: the color conversion helpers/types are a mess and needs sorting out.
+ - color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
+
+ - plot: full featured plot/graph api w/ scrolling, zooming etc. all bell & whistle. why not!
+ - plot: PlotLines() should use the polygon-stroke facilities, less vertices (currently issues with averaging normals)
+ - plot: make it easier for user to draw extra stuff into the graph (e.g: draw basis, highlight certain points, 2d plots, multiple plots)
+ - plot: "smooth" automatic scale over time, user give an input 0.0(full user scale) 1.0(full derived from value)
+ - plot: option/feature: draw the zero line
+ - plot: option/feature: draw grid, vertical markers
+ - plot: option/feature: draw unit
+ - plot: add a helper e.g. Plot(char* label, float value, float time_span=2.0f) that stores values and Plot them for you - probably another function name. and/or automatically allow to plot ANY displayed value (more reliance on stable ID)
+
+ - clipper: ability to force display 1 item in the list would be convenient (for patterns where we need to set active id etc.)
+ - clipper: ability to disable the clipping through a simple flag/bool.
+ - clipper: ability to run without knowing full count in advance.
+ - clipper: horizontal clipping support. (#2580)
+
+ - separator: expose flags (#759)
+ - separator: width, thickness, centering (#1643)
+ - splitter: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
+
+ - dock: merge docking branch (#2109)
+ - dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code.
+
+ - tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.
+ - tabs: persistent order/focus in BeginTabBar() api (#261, #351)
+
+ - image/image button: misalignment on padded/bordered button?
+ - image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
+ - image button: not taking an explicit id can be problematic. (#2464, #1390)
+ - button: provide a button that looks framed. (?)
+ - slider/drag: ctrl+click when format doesn't include a % character.. disable? display underlying value in default format? (see TempInputTextScalar)
+ - slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
+ - slider: initial absolute click is imprecise. change to relative movement slider (same as scrollbar). (#1946)
+ - slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
+ - slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
+ - slider: relative dragging? + precision dragging
+ - slider: step option (#1183)
+ - slider style: fill % of the bar instead of positioning a drag.
+ - knob: rotating knob widget (#942)
+ - drag float: power/logarithmic slider and drags are weird. (#1316)
+ - drag float: up/down axis
+ - drag float: power != 0.0f with current value being outside the range keeps the value stuck.
+ - drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
+
+ - combo: use clipper: make it easier to disable clipper with a single flag.
+ - combo: flag for BeginCombo to not return true when unchanged (#1182)
+ - combo: a way/helper to customize the combo preview (#1658)
+ - combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
+ - listbox: refactor and clean the begin/end api
+ - listbox: multiple selection.
+ - listbox: unselect option (#1208)
+ - listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (wip stash)
+ - listbox: user may want to initial scroll to focus on the one selected value?
+ - listbox: expose hovered item for a basic ListBox
+ - listbox: keyboard navigation.
+ - listbox: disable capturing mouse wheel if the listbox has no scrolling. (#1681)
+ - listbox: scrolling should track modified selection.
+ - listbox: future api should allow to enable horizontal scrolling (#2510)
+
+!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
+ - popups/modal: make modal title bar blink when trying to click outside the modal
+ - popups: reopening context menu at new position should be the behavior by default? (equivalent to internal OpenPopupEx() with reopen_existing=true) (~#1497)
+ - popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
+ - popups: clicking outside (to close popup) and holding shouldn't drag window below.
+ - popups: add variant using global identifier similar to Begin/End (#402)
+ - popups: border options. richer api like BeginChild() perhaps? (#197)
+ - tooltip: drag and drop with tooltip near monitor edges lose/changes its last direction instead of locking one. The drag and drop tooltip should always follow without changing direction.
+ - tooltip: tooltip that doesn't fit in entire screen seems to lose their "last preferred direction" and may teleport when moving mouse.
+ - tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
+ - tooltip: tooltips with delay timers? or general timer policy? (instantaneous vs timed): IsItemHovered() with timer + implicit aabb-id for items with no ID. (#1485)
+
+ - menus: calling BeginMenu() twice with a same name doesn't append as Begin() does for regular windows (#1207)
+ - menus: menu bars inside modal windows are acting weird.
+ - status-bar: add a per-window status bar helper similar to what menu-bar does.
+ - shortcuts: local-style shortcut api, e.g. parse "&Save"
+ - shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
+ - shortcuts: programmatically access shortcuts "Focus("&Save"))
+ - menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
+ - menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
+ - menus: could merge draw call in most cases (how about storing an optional aabb in ImDrawCmd to move the burden of merging in a single spot).
+
+ - text: selectable text (for copy) as a generic feature (ItemFlags?)
+ - text: proper alignment options in imgui_internal.h
+ - text: it's currently impossible to have a window title with "##". perhaps an official workaround would be nice. \ style inhibitor? non-visible ascii code to insert between #?
+ - text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT
+ - text: refactor TextUnformatted (or underlying function) to more explicitly request if we need width measurement or not
+ - text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
+ - text/wrapped: should be a more first-class citizen, e.g. wrapped text within a Selectable with known width
+ - text/wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
+
+ - tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
+ - tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
+ - tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
+ - tree node: tweak color scheme to distinguish headers from selected tree node (#581)
+ - tree node: leaf/non-leaf highlight mismatch.
+ - tree node: _NoIndentOnOpen flag? would require to store a per-depth bit mask to store info for pop (or whatever is cheaper)
+ - tree node/opt: could avoid formatting when clipped (flag assuming we don't care about width/height, assume single line height?)
+
+ - settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
+ - settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
+ - settings/persistence: helpers to make TreeNodeBehavior persist (even during dev!) - may need to store some semantic and/or data type in ImGuiStoragePair
+
+ - style: better default styles. (#707)
+ - style: add a highlighted text color (for headers, etc.)
+ - style: border types: out-screen, in-screen, etc. (#447)
+ - style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
+ - style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
+ - style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
+ - style: global scale setting.
+ - style: FramePadding could be different for up vs down (#584)
+ - style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
+ - style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
+ - style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
+ - style editor: color child window height expressed in multiple of line height.
+
+ - log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
+ - log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
+ - log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
+ - log: obsolete LogButtons() all together.
+ - log: LogButtons() options for specifying depth and/or hiding depth slider
+
+ - filters: set a current filter that tree node can automatically query to hide themselves
+ - filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
+ - filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
+
+ - drag and drop: drag tooltip hovering over source widget with IsItemHovered/SetTooltip flickers.
+ - drag and drop: fix/support/options for overlapping drag sources.
+ - drag and drop: releasing a drop shows the "..." tooltip for one frame - since e13e598 (#1725)
+ - drag and drop: drag source on a group object (would need e.g. an invisible button covering group in EndGroup) https://twitter.com/paniq/status/1121446364909535233
+ - drag and drop: have some way to know when a drag begin from BeginDragDropSource() pov. (see 2018/01/11 post in #143)
+ - drag and drop: allow preview tooltip to be submitted from a different place than the drag source. (#1725)
+ - drag and drop: allow using with other mouse buttons (where activeid won't be set). (#1637)
+ - drag and drop: make it easier and provide a demo to have tooltip both are source and target site, with a more detailed one on target site (tooltip ordering problem)
+ - drag and drop: demo with reordering nodes (in a list, or a tree node). (#143)
+ - drag and drop: test integrating with os drag and drop (make it easy to do a naive WM_DROPFILE integration)
+ - drag and drop: allow for multiple payload types. (#143)
+ - drag and drop: make payload optional? payload promise? (see 2018/01/11 post in #143)
+ - drag and drop: (#143) "both an in-process pointer and a promise to generate a serialized version, for whether the drag ends inside or outside the same process"
+ - drag and drop: feedback when hovering a region blocked by modal (mouse cursor "NO"?)
+
+ - node/graph editor (#306)
+ - pie menus patterns (#434)
+ - markup: simple markup language for color change? (#902)
+
+ - font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype)
+ - font: free the Alpha buffer if user only requested RGBA.
+!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
+ - font: for the purpose of RenderTextEllipsis(), it might be useful that CalcTextSizeA() can ignore the trailing padding?
+ - font: a CalcTextHeight() helper could run faster than CalcTextSize().y
+ - font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
+ - font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data
+ - font: make it easier to submit own bitmap font (same texture, another texture?). (#2127, #2575)
+ - font: PushFontSize API (#1018)
+ - font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
+ - font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width
+ - font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.
+ - font/demo: demonstrate use of ImFontGlyphRangesBuilder.
+ - font/atlas: add a missing Glyphs.reserve()
+ - font/atlas: incremental updates
+ - font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
+ - font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
+ - font/draw: need to be able to specify wrap start position.
+ - font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines)
+ - font/draw: underline, squiggle line rendering helpers.
+ - font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct), would save on cache line.
+ - font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
+ - font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
+ - font: fix AddRemapChar() to work before atlas  has been built.
+ - font: what would it take to support codepoint higher than 0xFFFF? (smileys, etc.) (#2538, #2541)
+ - font: (api breaking) remove "TTF" from symbol names. also because it now supports OTF.
+ - font/opt: Considering storing standalone AdvanceX table as 16-bit fixed point integer?
+ - font/opt: Glyph currently 40 bytes (2+9*4). Consider storing UV as 16 bits integer? (->32 bytes). X0/Y0/X1/Y1 as 16 fixed-point integers? Or X0/Y0 as float and X1/Y1 as fixed8_8?
+
+ - nav: some features such as PageUp/Down/Home/End should probably work without ImGuiConfigFlags_NavEnableKeyboard? (where do we draw the line?)
+ - nav: configuration flag to disable global shortcuts (currently only CTRL-Tab) ?
+ - nav: Home/End behavior when navigable item is not fully visible at the edge of scrolling? should be backtrack to keep item into view?
+ - nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
+ - nav: wrap around logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
+ - nav: patterns to make it possible for arrows key to update selection
+ - nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
+ - nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
+ - nav: ESC within a menu of a child window seems to exit the child window.
+ - nav: NavFlattened: ESC on a flattened child should select something.
+ - nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
+ - nav: NavFlattened: init request doesn't select items that are part of a NavFlattened child
+ - nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
+ - nav: Left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
+ - nav/menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
+ - nav/menus: allow pressing Menu to leave a sub-menu.
+ - nav/menus: a way to access the main menu bar with Alt? (currently needs CTRL+TAB)
+ - nav/menus: when using the main menu bar, even though we restore focus after, the underlying window loses its title bar highlight during menu manipulation. could we prevent it?
+ - nav/menus: main menu bar currently cannot restore a NULL focus. Could save NavWindow at the time of being focused, similarly to what popup do?
+ - nav: simulate right-click or context activation? (SHIFT+F10)
+ - nav: tabs should go through most/all widgets (in submission order?).
+ - nav: when CTRL-Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
+ - nav: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys.
+ - nav: when activating a button that changes label (without a static ID) or disappear, can we somehow automatically recover into a nearest highlight item?
+ - nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
+ - focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
+ - focus: SetKeyboardFocusHere() on with >= 0 offset could be done on same frame (else latch and modulate on beginning of next frame)
+ - focus: unable to use SetKeyboardFocusHere() on clipped widgets. (#787)
+
+ - inputs: we need an explicit flag about whether the imgui window is focused, to be able to distinguish focused key releases vs alt-tabbing all release behaviors.
+ - inputs: rework IO system to be able to pass actual ordered/timestamped events. use an event queue? (~#335, #71)
+ - inputs: support track pad style scrolling & slider edit.
+ - inputs/io: backspace and arrows in the context of a text input could use system repeat rate.
+ - inputs/io: clarify/standardize/expose repeat rate and repeat delays (#1808)
+ - inputs: add mouse cursor for unavailable/no? IDC_NO/SDL_SYSTEM_CURSOR_NO.
+ - inputs/scrolling: support for smooth scrolling (#2462, #2569)
+
+ - misc: idle: expose "woken up" boolean (set by inputs) and/or animation time (for cursor blink) for back-end to be able stop refreshing easily.
+ - misc: idle: if cursor blink if the _only_ visible animation, core imgui could rewrite vertex alpha to avoid CPU pass on ImGui:: calls.
+ - misc: idle: if cursor blink if the _only_ visible animation, could even expose a dirty rectangle that optionally can be leverage by some app to render in a smaller viewport, getting rid of much pixel shading cost.
+ - misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
+ - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
+ - misc: PushItemFlag(): add a flag to disable keyboard capture when used with mouse? (#1682)
+ - misc: use more size_t in public api?
+ - misc: possible compile-time support for string view/range instead of char* would e.g. facilitate usage with Rust (#683)
+ - misc: possible compile-time support for wchar_t instead of char*?
+
+ - backend: bgfx? https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0
+ - emscriptem: with refactored examples, we could provide a direct imgui_impl_emscripten platform layer (see eg. https://github.com/floooh/sokol-samples/blob/master/html5/imgui-emsc.cc#L42)
+
+ - remote: make a system like RemoteImGui first-class citizen/project (#75)
+
+ - demo: find a way to demonstrate textures in the examples application, as it such a common issue for new users.
+ - demo: demonstrate using PushStyleVar() in more details.
+ - demo: add vertical separator demo
+ - demo: add virtual scrolling example?
+ - demo: demonstrate Plot offset
+ - demo: window size constraint: square demo is broken when resizing from edges (#1975), would need to rework the callback system to solve this
+ - examples: window minimize, maximize (#583)
+ - examples: provide a zero frame-rate/idle example.
+ - examples: apple: example_apple should be using modern GL3.
+ - examples: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // issue: DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)
+ - examples: opengl: rename imgui_impl_opengl2 to impl_opengl_legacy and imgui_impl_opengl3 to imgui_impl_opengl? (#1900)
+ - examples: opengl: could use a single vertex buffer and glBufferSubData for uploads?
+ - examples: opengl: explicitly disable GL_STENCIL_TEST in bindings.
+ - examples: vulkan: viewport: support for synchronized swapping of multiple swap chains.
+ - optimization: replace vsnprintf with stb_printf? or enable the defines/infrastructure to allow it (#1038)
+ - optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
+ - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
+ - optimization: fully covered window (covered by another with non-translucent bg + WindowRounding worth of padding) may want to clip rendering.
+ - optimization: use another hash function than crc32, e.g. FNV1a
+ - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
+ - optimization: turn some the various stack vectors into statically-sized arrays
