I believe that Andrew Certain's problem can be solved with the routine
`swapinterval', it sets the *minimum* no. of vertical retraces b/n swapbuffers.

As long as you *know* that your drawing will be finished by
the interval you specify you will stay in sync. (Otherwise, you may get
a left<->right switch!)

On gsync, I don't understand Thant Tessman's comment -- surely a swapbuffer
doesn't happen until a vertical retrace anyhow -- so the gsync is redundant
right?
