Added an ifdef so that if you
#define SDL_NO_COMPAT
before you include SDL.h then SDL_compat.h will never be included in your code.
This is useful for making sure that your code uses only SDL 1.3 features.
It is also handy for finding things that are in SDL_compat.h that belong elsewhere.

The hardware will wait for vertical retrace, and then swap video buffers before the next video surface blit or lock will return\&.
