Current implementation of the IsInGameThread() doesn't make exceptions for a loading thread and lazy initialization of the Unreal resources ensures that plugin doesn't do any work before the game starts.
- Added SImGuiLayout to resets layout and house SImGuiWidget.
- Module manager creates SImGuiLayout instead of SImGuiWidget (eventually it should be replaced with a higher level object, like AHUD).
- Reworked ImGui canvas dragging and scaling and moved to SImGuiCanvasControl.
- Removed dependency on ImGui internal cursor data. New presentation is cleaner and doesn't use cursor data.
- Rendering code could be simplified after layout reset provided by SImGuiLayout.
- SImGuiWidget still handles input, rendering of ImGui draw data and activation of SImGuiCanvasControl.
- All widgets are in own subfolder.
- Divided ImGui settings into UImGuiSettings persistent object and FImGuiModuleSettings proxy that provides interface for other classes and handles delayed loading of UImGuiSettings.
- Removed from FImGuiModuleProperties and FImGuiModuleCommands direct dependencies on UImGuiSettings.
- Simplified FImGuiModuleProperties making it more robust when moving data after hot-reloading.
- Inverted binding logic by injecting FImGuiModuleProperties and FImGuiModuleCommands into FImGuiModuleSettings and letting it take care of synchronization. Dependencies are setup by module manager.
- Added to module manager FImGuiModuleSettings and interface to access it.
- Cleaned interface of FImGuiInputHandlerFactory and removed direct dependency on settings.
- Removed ImGui Module Properties singleton interface and released construction constraints.
- Added ImGui Module Properties to ImGui Module Manager.
- Moved ImGui Demo to ImGui Module Manager.
- ImGui Demo and ImGui Module Commands keep reference to ImGui Module Manager that gives them access to properties.
- Moved property variables to ImGui Module Properties.
- Moved console command to ImGui Module Commands (one for now but more will be added).
- ImGui Module Commands is created by ImGui Module Manager, what means that commands are registered after module is loaded and unregistered when it is unloaded.
- Updated settings to allow more convenient use: Added global pointer to default object and event raised when it is loaded.
- Split tick and textures initializations.
- Supporting deferred tick initialization, if Slate application is not ready during module startup.
- Textures are lazy-loaded before the first use.
- ImGui Context Manager initializes font atlas to make sure that ImGui resources are always initialized.
- Added to ImGui Context Proxy a name that is mapped to ini file set in ImGui context.
- ImGui Context Manager generates unique context names from world type and context index.
- Refactored ImGui Context Manager to have a cleaner separation between editor and non-editor bits.
- Fixed context update rules in ImGui Context Manager.
- Changed widgets management in ImGui Module Manager to allow automatic garbage collection after viewports are closed and manual removal when module is shutting down.
- ImGui Widgets are in full control of communication with context proxies.
- Added basic world context utilities.
- Refactored world context index utilities and replaced ambiguous 'default context index' with 'editor' and 'game' ones.
- Added ImGui Context Manager to create and manage ImGui Context Proxies.
- Changed ImGui Context Proxy to dynamically create context and allow pairing with input state.
- Changed ImGui Module Manager to create one widget per context.
- Changed ImGui Widget to work in different input modes.
- Changed ImGui Input State to allow partial reset (only mouse or keyboard).
- Added ImGui Input State to collect and store input updates.
- Changed Slate ImGui Widget to handle Slate input events and store them in input state.
- Changed ImGui Context Proxy to copy input state to its context.
- Added ImGui Module Manager that that implements module logic and manages other module resources.
- Added Texture Manager to manage texture resources and maps them to index that can be passed to ImGui context.
- Added Context Proxy that represents and manages a single ImGui context.
- Added Slate ImGui Widget to render ImGui output.
