annotate src/joystick/darwin/SDL_sysjoystick.c @ 4099:822f9624f984 SDL-1.2

Brian Fisher fixed bug #513 If an app requests a 24-bit opengl mode on a machine with a 32-bit desktop with the windib video backend, then when exiting fullscreen the desktop resolution is not restored The reason this is, is because the windib backend restores the desktop resolution when exiting fullscreen in DIB_SetVideoMode when it finds that the last request was for fullscreen by checking the original flags on the video surface. However, if the bits per pixel requested is different than current surface, the video surface is recreated and the original video flags are lost. So the check to see if we were exiting fullscreen fails. below is a patch to SDL_dibvideo.c that solves the problem by using the original flags in all cases. thanks!
