Mac: Send a window resize event when the window's backing scale factor changes.
The backing scale factor can change when the window moves between retina and non-retina displays.
The only other way to detect such a change is to compare the output of SDL_GL_GetDrawableSize or SDL_GetRendererOutputSize every frame, which is less than desirable, especially since the necessary app logic is likely already being executed when a window resize event is received.
