sdl-ios-xcode: src/video/ps2gs/SDL

annotate src/video/ps2gs/SDL_gsvideo.c @ 3936:c5c3c772f5aa SDL-1.2

Let app set SDL_VIDEO_ALLOW_SCREENSAVER environment variable to override SDL's attempt to disable screen savers. Works for Quartz (Mac OS X) and X11. Need a formal API for this in 1.3, still. Fixes Bugzilla #415.
