// Implemented features:
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// [X] Platform: OSX clipboard is supported within core Dear ImGui (no specific code in this backend).
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// Issues:
// [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..
