SDL_GetAppState() correction when toggling fullscreen on OSX. Patch by me to address this comment on the SDL mailing list: "There appears to be a serious bug with SDL_GetAppState on OS X (10.3.9). When first running in windowed mode and then switching to full screen mode by calling SDL_SetVideoMode, SDL_GetAppState returns 4 (SDL_APPACTIVE) instead of 7 (SDL_APPMOUSEFOCUS | SDL_APPINPUTFOCUS | SDL_APPACTIVE). However, the SDL application clearly does have the keyboard focus, since it is able to receive keyboard events." --ryan.
