loader or link to a dynamic library version. This limitation may be removed
in a future version of SDL.

Additionally, a newly created window might not have mouse focus (but keyboard
focus only). By default, SDL will ignore mouse clicks that activate a window,
for its events queue thus a click in a newly created / out of focus window will
not create an event.
Use `SDL_SetHint(SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, "1");` to override this and
to receive an event from [SDL_PollEvent](SDL_PollEvent)() in such case.

## Version

This function is available since SDL 2.0.0.
