- 2022/01/17 (1.87) - inputs: reworked mouse IO.
- Backend writing to io.MousePos -> backend should call io.AddMousePosEvent()
- Backend writing to io.MouseDown[] -> backend should call io.AddMouseButtonEvent()
- Backend writing to io.MouseWheel -> backend should call io.AddMouseWheelEvent()
- Backend writing to io.MouseHoveredViewpot -> backend should call io.AddMouseViewportEvent() [Docking branch only]
- 2022/01/10 (1.87) - inputs: reworked keyboard IO. Removed io.KeyMap[], io.KeysDown[] in favor of calling io.AddKeyEvent(). Removed GetKeyIndex(), now unecessary. All IsKeyXXX() functions now take ImGuiKey values. All features are still functional until IMGUI_DISABLE_OBSOLETE_KEYIO is defined. Read Changelog and Release Notes for details.
- IsKeyPressed(MY_NATIVE_KEY_XXX) -> use IsKeyPressed(ImGuiKey_XXX)
- IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) -> use IsKeyPressed(ImGuiKey_XXX)
