* SDL_HINT_IDLE_TIMER_DISABLED - use SDL_DisableScreenSaver instead
* SDL_HINT_IME_SUPPORT_EXTENDED_TEXT - the normal text editing event has extended text
* SDL_HINT_MOUSE_RELATIVE_SCALING - mouse coordinates are no longer automatically scaled by the SDL renderer
* SDL_HINT_RENDER_LOGICAL_SIZE_MODE - the logical size mode is explicitly set with SDL_SetRenderLogicalPresentation()
* SDL_HINT_RENDER_BATCHING - Render batching is always enabled, apps should call SDL_FlushRenderer() before calling into a lower-level graphics API.
* SDL_HINT_RENDER_LOGICAL_SIZE_MODE - the logical size mode is explicitly set with SDL_SetRenderLogicalPresentation()
* SDL_HINT_VIDEO_FOREIGN_WINDOW_OPENGL - replaced with the "opengl" property in SDL_CreateWindowWithProperties()
* SDL_HINT_VIDEO_FOREIGN_WINDOW_VULKAN - replaced with the "vulkan" property in SDL_CreateWindowWithProperties()
* SDL_HINT_VIDEO_HIGHDPI_DISABLED - high DPI support is always enabled
