Christian Soffke 60f3283f48 sdl: make window resizable, enable high DPI 
Tested on Linux, MacOS, and Windows.

On MacOS and Windows, we constrain the window's aspect
ratio by adjusting the size when responding to resize
events.

On Linux, I've not found a way to do so, that doesn't
result in fairly stuttery behavior and weird jumpy
behavior of the resize handle, possibly depending
on your window manager. So, black bars are displayed
around the content.
Maybe someone, at some point, finds a way.
(SDL3 seems to have SDL_SetWindowAspectRatio)

When the window is in fullscreen, black bars are
display necessarily, of course, on all systems,
unless the player GUI has exactly the same aspect
ratio as the screen...
