annotate src/video/directfb/SDL_DirectFB_opengl.c @ 5004:0c72ae7b7cb2

Added native atomic operations for Windows, Mac OS X, and gcc compiler intrinsics. Changed the CAS return value to bool, so it's efficient with OSAtomicCompareAndSwap32Barrier() Added an atomic test adapted from code by Michael Davidsaver
