119 ><P
120 >On hardware that supports double-buffering, this function sets up a flip
121 and returns. The hardware will wait for vertical retrace, and then swap
122 video buffers before the next video surface blit or lock will return.
123 On hardware that doesn't support double-buffering, this is equivalent
124 to calling <A
