I think your other patch is fine.

But with regards to this problem: Ouch, that seems to be a very ugly one.
If I get that right, SDL_GetMouseState() seems to provide us with the
*absolute* desktop mouse coordinates, not the ones relative to our drawing
area (like we seem to get in the SDL_MOUSEBUTTONDOWN event later). So we
likely have to substract the width of the left (or height of the upper)
black border in fullscreen from the mouse coordinates. That's getting very,
very ugly, especially since I haven't found a good way to determine the
size of that border yet. Thus no clue yet how to solve that properly ...
any suggestions?
