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

| when |
| setting the video mode for this function to perform hardware flipping.</P |
