I should probably look into the way VirtualGL handles invisible windows in general, since there may be some unexpected behavior lurking in there. I think that it's probably incorrect to establish and use a pbwin instance on the window unless it is visible, because pbwin's purpose is essentially making the off-screen (Pbuffer) pixels visible. ------------------------------------------------------------------------------ Write once.
