Subject: SDL OSX fullscreen FIX
the attached patch fixes the fullscreen problems on SDL/OSX. The cause
was that click events are bounded by winRect. Now, winRect is set to
the size of the video surface. But if you e.g. request a 640x420
surface, you might get a 640x480 "real" surface. Still,
SDL_VideoSurface->h will be set to 420! Thus, the upper 60 pixels in my
example received no mouse down events.
My fix simply disables this clipping when in full screen mode - after
all, all clicks then should be inside the screen surface. Higher SDL
functions ensure that the coordinates then are clipped to 640x420. It
works fine in all my tests here. I don't know if it's the right thing
to do in multi screen scenarios, though.
