 Status
 ------
 ImGui version: 1.65
 Supported engine version: 4.20.2*
 \* *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. Right now it should be at least backward compatible with the engine version 4.15.*

 VERSION 1.65 (Released 2018-09-06)
 -----------------------------------------------------------------------
 VERSION 1.61 WIP
 Breaking Changes:
 (IN PROGRESS, WILL ADD TO THIS LIST AS WE WORK ON 1.61)
- - Misc: IM_DELETE() helper function added in 1.60 doesn't set the input pointer to NULL, more consistent with standard expectation and allows passing r-value.
+- Renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and
  stb_rect_pack.h to imstb_rectpack.h. If you were conveniently using the imgui copy of those
  STB headers in your project, you will have to update your include paths. (#1718, #2036)
  The reason for this change is to avoid conflicts for projects that may also be importing
  their own copy of the STB libraries. Note that imgui's copy of stb_textedit.h is modified.
 - Renamed io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
 Other Changes:
 (IN PROGRESS, WILL ADD TO THIS LIST AS WE WORK ON 1.61)
- Window: Fixed default proportional item width lagging by one frame on resize.
+- This is a minor release following the 1.64 refactor, with a little more shuffling of code.
 - Clarified and improved the source code sectioning in all files (easier to search or browse sections).
 - Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system.
  Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)
 - Fixed a build issue with non-Cygwin GCC under Windows.
 - Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent.
 - Examples: OpenGL3: Fixed error condition when using the GLAD loader. (#2059, #2002). [@jiri]
 -----------------------------------------------------------------------
 VERSION 1.64 (Released 2018-08-31)
 -----------------------------------------------------------------------
 Changes:
 - Moved README, CHANGELOG and TODO files to the docs/ folder.
  If you are updating dear imgui by copying files, take the chance to delete the old files.
 - Added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp.
  Re-ordered some of the code remaining in imgui.cpp.
  NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTIONS HAS BEEN MOVED.
  Because of this, any local modifications to imgui.cpp will likely conflict when you update.
  If you have any modifications to imgui.cpp, it is suggested that you first update to 1.63, then
  isolate your patches. You can peak at imgui_widgets.cpp from 1.64 to get a sense of what is included in it,
  then separate your changes into several patches that can more easily be applied to 1.64 on a per-file basis.
  What I found worked nicely for me, was to open the diff of the old patches in an interactive merge/diff tool,
  search for the corresponding function in the new code and apply the chunks manually. 
 - As a reminder, if you have any change to imgui.cpp it is a good habit to discuss them on the github,
  so a solution applicable on the Master branch can be found. If your company has changes that you cannot
  disclose you may also contact me privately.
 -----------------------------------------------------------------------
 VERSION 1.63 (Released 2018-08-29)
 -----------------------------------------------------------------------
 Breaking Changes:
 - Style: Renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
 - Changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecision over time.
 - Removed per-window ImGuiWindowFlags_ResizeFromAnySide Beta flag in favor `io.ConfigResizeWindowsFromEdges=true` to enable the feature globally. (#1495)
  The feature is not currently enabled by default because it is not satisfying enough, but will eventually be.
 - InputText: Renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. 
  Kept redirection types (will obsolete). 
 - InputText: Removed ImGuiTextEditCallbackData::ReadOnly since it is a duplication of (ImGuiTextEditCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
 - Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. 
  Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
 - Renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to io.ConfigMacOSXBehaviors for consistency. (#1427, #473)
 - Removed obsolete redirection functions: CollapsingHeader() variation with 2 bools - marked obsolete in v1.49, May 2016.
 Other Changes:
 - ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat).
 - ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.
 - Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. The change is motivated by upcoming Docking features. (#787)
 - Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787)
  While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the ImGuiWindow_NoNavFocus flag.
 - Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909)
 - Window: Added global io.ConfigResizeWindowsFromEdges option to enable resizing windows from their edges and from the lower-left corner. (#1495)
 - Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well. 
 - Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool returned by most widgets.
  It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034)
 - InputText: Added support for buffer size/capacity changes via the ImGuiInputTextFlags_CallbackResize flag. (#2006, #1443, #1008).
 - InputText: Fixed not tracking the cursor horizontally when modifying the text buffer through a callback.
 - InputText: Fixed minor off-by-one issue when submitting a buffer size smaller than the initial zero-terminated buffer contents.
 - InputText: Fixed a few pathological crash cases on single-line InputText widget with multiple millions characters worth of contents. 
  Because the current text drawing function reserve for a worst-case amount of vertices and how we handle horizontal clipping,
  we currently just avoid displaying those single-line widgets when they are over a threshold of 2 millions characters, 
  until a better solution is found.
 - Drag and Drop: Fixed an incorrect assert when dropping a source that is submitted after the target (bug introduced with 1.62 changes 
  related to the addition of IsItemDeactivated()). (#1875, #143)
 - Drag and Drop: Fixed ImGuiDragDropFlags_SourceNoDisableHover to affect hovering state prior to calling IsItemHovered() + fixed description. (#143)
 - Drag and Drop: Calling BeginTooltip() between a BeginDragSource()/EndDragSource() or BeginDropTarget()/EndDropTarget() uses adjusted tooltip
  settings matching the one created when calling BeginDragSource() without the ImGuiDragDropFlags_SourceNoPreviewTooltip flag. (#143)
 - Drag and Drop: Payload stays available and under the mouse if the source stops being submitted, however the tooltip is replaced by "...". (#1725)
 - Drag and Drop: Added ImGuiDragDropFlags_SourceAutoExpirePayload flag to force payload to expire if the source stops being submitted. (#1725, #143).
 - IsItemHovered(): Added ImGuiHoveredFlags_AllowWhenDisabled flag to query hovered status on disabled items. (#1940, #211)
 - Selectable: Added ImGuiSelectableFlags_Disabled flag in the public API. (#211)
 - ColorEdit4: Fixed a bug when text input or drag and drop leading to unsaturated HSV values would erroneously alter the resulting color. (#2050)
 - Misc: Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2006, #1443, #1008)
 - Misc: Added IMGUI_VERSION_NUM for easy compile-time testing. (#2025)
 - Misc: Added ImGuiMouseCursor_Hand cursor enum + corresponding software cursor. (#1913, 1914) [@aiekick, @ocornut] 
 - Misc: Tweaked software mouse cursor offset to match the offset of the corresponding Windows 10 cursors.
 - Made assertion more clear when trying to call Begin() outside of the NewFrame()..EndFrame() scope. (#1987)
 - Fixed assertion when transitioning from an active ID to another within a group, affecting ColorPicker (broken in 1.62). (#2023, #820, #956, #1875).
 - Fixed PushID() from keeping alive the new ID Stack top value (if a previously active widget shared the ID it would be erroneously kept alive).  
 - Fixed horizontal mouse wheel not forwarding the request to the parent window if ImGuiWindowFlags_NoScrollWithMouse is set. (#1463, #1380, #1502)
 - Fixed a include build issue for Cygwin in non-POSIX (Win32) mode. (#1917, #1319, #276)
 - ImDrawList: Improved handling for worst-case vertices reservation policy when large amount of text (e.g. 1+ million character strings)
  are being submitted in a single call. It would typically have crashed InputTextMultiline(). (#200)
 - OS/Windows: Fixed missing ImmReleaseContext() call in the default Win32 IME handler. (#1932) [@vby]
 - Metrics: Changed io.MetricsActiveWindows to reflect the number of active windows (!= from visible windows), which is useful
  for lazy/idle render mechanisms as new windows are typically not visible for one frame.
 - Metrics: Added io.MetricsRenderWindow to reflect the number of visible windows.
 - Metrics: Added io.MetricsActiveAllocations, moving away from the cross-context global counters than we previously used. (#1565, #1599, #586)
 - Demo: Added basic Drag and Drop demo. (#143)
 - Demo: Modified the Console example to use InsertChars() in the input text callback instead of poking directly into the buffer.
  Although this won't make a difference in the example itself, using InsertChars() will honor the resizing callback properly. (#2006, #1443, #1008).
 - Demo: Clarified the use of IsItemHovered()/IsItemActive() right after being in the "Active, Focused, Hovered & Focused Tests" section.
 - Examples: Tweaked the main.cpp of each example.
 - Examples: Metal: Added Metal rendering backend. (#1929, #1873) [@warrenm]
 - Examples: OSX: Added early raw OSX platform backend. (#1873) [@pagghiu, @itamago, @ocornut]
 - Examples: Added mac OSX & iOS + Metal example in example_apple_metal/. (#1929, #1873) [@warrenm]
 - Examples: Added mac OSX + OpenGL2 example in example_apple_opengl2/. (#1873)
 - Examples: OpenGL3: Added shaders more versions of GLSL. (#1938, #1941, #1900, #1513, #1466, etc.) 
 - Examples: OpenGL3: Tweaked the imgui_impl_opengl3.cpp to work as-is with Emscripten + WebGL 2.0. (#1941). [@o-micron] 
 - Examples: OpenGL3: Made the example app default to GL 3.0 + GLSL 130 (instead of GL 3.2 + GLSL 150) unless on Mac.
 - Examples: OpenGL3: Added error output when shaders fail to compile/link.
 - Examples: OpenGL3: Added support for glew and glad OpenGL loaders out of the box. (#2001, #2002) [@jdumas]
 - Examples: OpenGL2: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications. (#1996)
 - Examples: DirectX10, DirectX11: Fixed unreleased resources in Init and Shutdown functions. (#1944)
 - Examples: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility. (#1989) [@matt77hias]
 - Examples: Vulkan: Fixed handling of VkSurfaceCapabilitiesKHR::maxImageCount = 0 case. Tweaked present mode selections. 
 - Examples: Win32, Glfw, SDL: Added support for the ImGuiMouseCursor_Hand cursor.
 -----------------------------------------------------------------------
 VERSION 1.62 (Released 2018-06-22)
 -----------------------------------------------------------------------
 Breaking Changes:
 - TreeNodeEx(): The helper ImGuiTreeNodeFlags_CollapsingHeader flag now include ImGuiTreeNodeFlags_NoTreePushOnOpen. The flag was already set by CollapsingHeader(). 
  The only difference is if you were using TreeNodeEx() manually with ImGuiTreeNodeFlags_CollapsingHeader and without ImGuiTreeNodeFlags_NoTreePushOnOpen. 
  In this case you can remove the ImGuiTreeNodeFlags_NoTreePushOnOpen flag from your call (ImGuiTreeNodeFlags_CollapsingHeader & ~ImGuiTreeNodeFlags_NoTreePushOnOpen). (#1864)
  This also apply if you were using internal's TreeNodeBehavior() with the ImGuiTreeNodeFlags_CollapsingHeader flag directly.
 - ImFontAtlas: Renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish new smaller variants and discourage using the full set. (#1859)
 Other Changes:
 - Examples back-ends have been refactored to separate the platform code (e.g. Win32, Glfw, SDL2) from the renderer code (e.g. DirectX11, OpenGL3, Vulkan).
  The "Platform" bindings are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, etc.
  The "Renderer" bindings are in charge of: creating the main font texture, rendering imgui draw data.
      before: imgui_impl_dx11.cpp        --> after: imgui_impl_win32.cpp + imgui_impl_dx11.cpp
      before: imgui_impl_dx12.cpp        --> after: imgui_impl_win32.cpp + imgui_impl_dx12.cpp
      before: imgui_impl_glfw_gl3.cpp    --> after: imgui_impl_glfw.cpp + imgui_impl_opengl2.cpp
      before: imgui_impl_glfw_vulkan.cpp --> after: imgui_impl_glfw.cpp + imgui_impl_vulkan.cpp
      before: imgui_impl_sdl_gl3.cpp     --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl2.cpp
      before: imgui_impl_sdl_gl3.cpp     --> after: imgui_impl_sdl2.cpp + imgui_impl_opengl3.cpp etc.
  - The idea is what we can now easily combine and maintain back-ends and reduce code redundancy. Individual files are smaller and more reusable.
    Integration of imgui into a new/custom engine may also be easier as there is less overlap between "windowing / inputs" and "rendering" code, 
    so you may study or grab one half of the code and not the other.
  - This change was motivated by the fact that adding support for the upcoming multi-viewport feature requires more work from the Platform and Renderer 
    back-ends, and the amount of redundancy across files was becoming too difficult to maintain. If you use default back-ends, you'll benefit from an 
    easy update path to support multi-viewports later (for future ImGui 1.7x).
  - This is not strictly a breaking change if you keep your old bindings, but when you'll want to fully update your bindings, 
    expect to have to reshuffle a few things. 
  - Each example still has its own main.cpp which you may refer you to understand how to initialize and glue everything together.
  - Some frameworks (such as the Allegro, Marmalade) handle both the "platform" and "rendering" part, and your custom engine may as well.
  - Read examples/README.txt for details.
 - Added IsItemDeactivated() to query if the last item was active previously and isn't anymore. Useful for Undo/Redo patterns. (#820, #956, #1875)
 - Added IsItemDeactivatedAfterChange() [*EDIT* renamed to IsItemDeactivatedAfterEdit() in 1.63) if the last item was active previously, 
  is not anymore, and during its active state modified a value. Note that you may still get false positive (e.g. drag value and while 
  holding return on the same value). (#820, #956, #1875)
 - Nav: Added support for PageUp/PageDown (explorer-style: first aim at bottom/top most item, when scroll a page worth of contents). (#787)
 - Nav: To keep the navigated item in view we also attempt to scroll the parent window as well as the current window. (#787)
 - ColorEdit3, ColorEdit4, ColorButton: Added ImGuiColorEditFlags_NoDragDrop flag to disable ColorEditX as drag target and ColorButton as drag source. (#1826) 
 - BeginDragDropSource(): Offset tooltip position so it is off the mouse cursor, but also closer to it than regular tooltips, and not clamped by viewport. (#1739)
 - BeginDragDropTarget(): Added ImGuiDragDropFlags_AcceptNoPreviewTooltip flag to request hiding the drag source tooltip from the target site. (#143)
 - BeginCombo(), BeginMainMenuBar(), BeginChildFrame(): Temporary style modification are restored at the end of BeginXXX instead of EndXXX, to not affect tooltips and child windows.
 - Popup: Improved handling of (erroneously) repeating calls to OpenPopup() to not close the popup's child popups. (#1497, #1533, #1865).
 - InputTextMultiline(): Fixed double navigation highlight when scrollbar is active. (#787)
 - InputText(): Fixed Undo corruption after pasting large amount of text (Redo will still fail when undo buffers are exhausted, but text won't be corrupted).
 - SliderFloat(): When using keyboard/gamepad and a zero precision format string (e.g. "%.0f"), always step in integer units. (#1866)
 - ImFontConfig: Added GlyphMinAdvanceX/GlyphMaxAdvanceX settings useful to make a font appears monospaced, particularly useful for icon fonts. (#1869)
 - ImFontAtlas: Added GetGlyphRangesChineseSimplifiedCommon() helper that returns a list of ~2500 most common Simplified Chinese characters. (#1859) [@JX-Master, @ocornut]
 - Examples: OSX: Added imgui_impl_osx.mm binding to be used along with e.g. imgui_impl_opengl2.cpp. (#281, #1870) [@pagghiu, @itamago, @ocornut]
 - Examples: GLFW: Made it possible to Shutdown/Init the backend again (by reseting the time storage properly). (#1827) [@ice1000]
 - Examples: Win32: Fixed handling of mouse wheel messages to support sub-unit scrolling messages (typically sent by track-pads). (#1874) [@zx64]  
 - Examples: SDL+Vulkan: Added SDL+Vulkan example.
 - Examples: Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag. Added clipboard support. 
 - Examples: Allegro5: Unindexing buffers ourselves as Allegro indexed drawing primitives are buggy in the DirectX9 back-end (will be fixed in Allegro 5.2.5+).
 - Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301)
 - Examples: Vulkan: Reordered parameters ImGui_ImplVulkan_RenderDrawData() to be consistent with other bindings, a good occasion since we refactored the code. 
 - Examples: FreeGLUT: Added FreeGLUT bindings. Added FreeGLUT+OpenGL2 example. (#801)
 - Examples: The functions in imgui_impl_xxx.cpp are prefixed with IMGUI_IMPL_API (which defaults to IMGUI_API) to facilitate some uses. (#1888)
 - Examples: Fixed bindings to use ImGuiMouseCursor_COUNT instead of old name ImGuiMouseCursor_Count_ so they can compile with IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#1887) 
 - Misc: Updated stb_textedit from 1.09 + patches to 1.12 + minor patches.
 - Internals: PushItemFlag() flags are inherited by BeginChild().
 -----------------------------------------------------------------------
 VERSION 1.61 (Released 2018-05-14)
 -----------------------------------------------------------------------
 Breaking Changes:
 - DragInt(): The default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
  If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
  To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
  If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to you find them.
 - InputFloat(): Obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
  consistent with other functions. Kept redirection functions (will obsolete).
 - Misc: IM_DELETE() helper function added in 1.60 doesn't set the input pointer to NULL, more consistent with standard expectation and allows passing r-values.
 Other Changes:
 - Added DragScalar, DragScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
 - Added InputScalar, InputScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
 - Added SliderScalar, SliderScalarN: supports signed/unsigned, 32/64 bits, float/double data types. (#643, #320, #708, #1011)
 - Window: Fixed pop-ups/tooltips/menus not honoring style.DisplaySafeAreaPadding as well as it should have (part of menus displayed outside the safe area, etc.).
 - Window: Fixed windows using the ImGuiWindowFlags_NoSavedSettings flag from not using the same default position as other windows. (#1760)
 - Window: Relaxed the internal stack size checker to allow Push/Begin/Pop/.../End patterns to be used with PushStyleColor, PushStyleVar, PushFont without causing a false positive assert. (#1767)
 - Window: Fixed the default proportional item width lagging by one frame on resize.
 - Columns: Fixed a bug introduced in 1.51 where columns would affect the contents size of their container, often creating feedback loops when ImGuiWindowFlags_AlwaysAutoResize was used. (#1760)
 - Settings: Fixed saving an empty .ini file if CreateContext/DestroyContext are called without a single call to NewFrame(). (#1741)
 - Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory() to manually load/save .ini settings. (#923, #993)
 - Settings: Added io.WantSaveIniSettings flag, which is set to notify the application that e.g. SaveIniSettingsToMemory() should be called. (#923, #993)
 - Scrolling: Fixed a case where using SetScrollHere(1.0f) at the bottom of a window on the same frame the window height has been growing would have the scroll clamped using the previous height. (#1804)
 - MenuBar: Made BeginMainMenuBar() honor style.DisplaySafeAreaPadding so the text can be made visible on TV settings that don't display all pixels. (#1439) [@dougbinks]
 - InputText: On Mac OS X, filter out characters when the CMD modifier is held. (#1747) [@sivu]
 - InputText: On Mac OS X, support CMD+SHIFT+Z for Redo. CMD+Y is also supported as major apps seems to default to support both. (#1765) [@lfnoise]
- InputText: Fixed returning true when edition is canceled with ESC and the current buffer matches the initial value.
+- InputText: Fixed returning true when edition is cancelled with ESC and the current buffer matches the initial value.
- InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional "const char* format" parameter instead of "int decimal_precision". 
+- InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional "const char* format" parameter instead of "int decimal_precision".
  This allow using custom formats to display values in scientific notation, and is generally more consistent with other API. Obsoleted functions using the optional "int decimal_precision" parameter. (#648)
 - DragFloat, DragInt: Cancel mouse tweak when current value is initially past the min/max boundaries and mouse is pushing in the same direction (keyboard/gamepad version already did this).
 - DragFloat, DragInt: Honor natural type limits (e.g. INT_MAX, FLT_MAX) instead of wrapping around. (#708, #320)
 - DragFloat, SliderFloat: Fixes to allow input of scientific notation numbers when using CTRL+Click to input the value. (~#648, #1011)
 - DragFloat, SliderFloat: Rounding-on-write uses the provided format string instead of parsing the precision from the string, which allows for finer uses of %e %g etc. (#648, #642)
 - DragFloat: Improved computation when using the power curve. Improved lost of input precision with very small steps. Added an assert than power-curve requires a min/max range. (~#642)
 - DragFloat: The 'power' parameter is only honored if the min/max parameter are also setup.

 - Renamed `AlignFirstTextHeightToWidgets()` to `AlignTextToFramePadding()`. Kept inline redirection function (will obsolete).
 - Obsoleted the legacy 5 parameters version of Begin(). Please avoid using it. If you need a transparent window background, uses `PushStyleColor()`. The old size parameter there was also misleading and equivalent to calling `SetNextWindowSize(size, ImGuiCond_FirstTimeEver)`. Kept inline redirection function (will obsolete).
 - Obsoleted `IsItemHoveredRect()`, `IsMouseHoveringWindow()` in favor of using the newly introduced flags of `IsItemHovered()` and `IsWindowHovered()`. Kept inline redirection function (will obsolete). (#1382)
 - Obsoleted 'SetNextWindowPosCenter()' in favor of using 1SetNextWindowPos()` with a pivot value which allows to do the same and more. Keep inline redirection function.
 - Removed `IsItemRectHovered()`, `IsWindowRectHovered()` recently introduced in 1.51 which were merely the more consistent/correct names for the above functions which are now obsolete anyway. (#1382)
 - Changed `IsWindowHovered()` default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. (#1382)
 - Renamed imconfig.h's `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS` to `IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS`/`IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS` for consistency.

 _NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

 Frequently Asked Question (FAQ)
 -------------------------------
-<b>Where is the documentation?</b>
+**Where is the documentation?**
 - The documentation is at the top of imgui.cpp + effectively imgui.h. 
 - Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. 
 - Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. 
 - We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
-<b>Which version should I get?</b>
+**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.

-<b>Why the odd dual naming, "dear imgui" vs "ImGui"?</b>
+**Why the odd dual naming, "dear imgui" vs "ImGui"?**
 The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.

 You can control Dear ImGui with a gamepad, see the explanation in imgui.cpp about how to use the navigation feature (short version: map your gamepad inputs into the `io.NavInputs[]` array and set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad`).

 For touch inputs, you can increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little 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.
-<b>Can you create elaborate/serious tools with Dear ImGui?</b>
+**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 requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
-<b>Can you reskin the look of Dear ImGui?</b>
+**Can you reskin the look of Dear ImGui?**
 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. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):

-<b>Why using C++ (as opposed to C)?</b>
+**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 reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. 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 [Links](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to other languages.
