Yes... The driver actually contains that kind of code already. It's
used when rendering directly into a window (ie single buffered) that
is partially covered by other windows, so that the OpenGL area
becomes non-rectangular. (Seems like most drivers simply don't
support single buffering in windowed mode, thus avoiding this stuff
entirely.)
I accidentally found out because the retrace sync is done in the wrong
place. The driver ends up sync'ing once for each one of the sub
rectangles that the window is split into... *hehe*
