<DIV><FONT size=2 face=Arial><SPAN class=711341012-19072010>i have a question
about the logic of PBO usage in vtkOpenGLTexture. It seems that the current
implemetation make use of the PBO just the first render time or if the ivar
RenderWindow is not set. Otherweise the ivar SupportsPBO will be always reseted
to false during the ReleaseGraphicsResource() call in line 309, so the PBO
never used. Is it desired behavior? Or should the ReleaseGraphicsResource()
call be moved to line 255 before CheckHardwareSupport?</SPAN></FONT></DIV>
