sdl: improve window resizing on macOS

Browse source 
This enables smooth resizing of the window using a
fixed aspect ratio, instead of snapping into the
correct aspect ratio only when the resize operation
has finished, by using an SDL event filter that gets
events delivered during the resize operation
(whereas SDL_PollEvent blocks until done on macOS).
