- With the mouse sharing enabled, SImGuiWidget can update mouse position without enabling hit-tests. Actual input mode depends whether mouse cursor is hovering any ImGui window or not.
- Added to context proxy interface to read whether that context has mouse hovering any window.
- Added boilerplate code to support mouse sharing settings, properties and commands.
- Moved responsibility for updating input state from the widget to the input handler.
- Changed the widget to fully delegate input events to the input handler and only manage its own input state.
- Changed the input handler interface to allow handling of all the necessary input events.
- Changed the input handler interface to use FReply as a response type and removed obsolete FImGuiInputResponse.
Moving input state to context proxy decouples it a bit from a particular input source and although not used right now, it allows multiple sources to send input in parallel.
- Removed mouse status update.
- Removed mouse notifications.
- Removed unused function to copy modifier keys on mouse events (key down/up versions are still in use).
- 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.
