Doesn't need vertical retrace!

[Rub�n]

        I've discovered a nice thing, at least on my card, a S3 Virge, all
accel drawing is syncronised with the vertical retrace, so, I've discovered
a temporal solution for my problems:
        I only need to draw on the second video memory page all I want, and
when I should change the panning to be on this page, instead of this, I do a
copybox to the first one... It will be sincronised with VR.
        I've tested it and it's REALLY nice, now my 3D cube rotates really
smooth !
        Well, maybe it came into your mind before (its very simple), but
none of you told me this solution...
