That's right, but in fact, if you think at it, a blocking vsync() function is
not so cool, because you can loose a lot of usefull time, waiting the sync.
And a vsync() function wich return immediately but do the fliping at the next
vertical refresh is not good too, because after this call, if you start
drawing on what you think is the offscreen windows but which is still
displayed, you will have bad results...
Maybe, the best thing is to have a vsync event, which say "hey, it's time to
flip the screen" or, to be sure the fliping occur at the right timing because
while handling the event it could be too late, it is maybe better to have an
event which just say : "hey, i've just finished doing the fliiping, you can
now draw on the offscreen window".
