Subject: Moved pbuffer creation support from MacOSXOnscreenGLDrawable to
MacOSXGLContextFactory. This completes the transition from creating pbuffers
as a subordinate object of a GLCanvas to creating them as standalone
GLDrawables. Deleted code from GLAutoDrawable and all implementations related
to pbuffer instantiation.
