The proper way to set up Performer with dmedia pbuffers, is through the calls
pfPWinWSDrawable() and pfPWinGLCxt(). The drawable is the pbuffer and the
context can be created with glXCreateContextWithConfigSGIX().
The problem is that only Performer 2.2 can get a pbuffer as a drawable.
Performer 2.1 will crash on that. The way to work around this is creating a
plain old pfPipeWindow, but call glXMakeCurrent with your pbuffer and context
at the beginning of the drawing frame.
