FYI, Performer versions 2.0.3/2.1.1 shipped in IRIX6.3 and
versions 2.0.4/2.1.2 to be shipped in IRIX6.4 and soon to be
released patch 1696 for IRIX6.2 supports the work-around of
handing pf{P}WinWSDrawable a pfbuffer and pf{P}WinFBConfig a
GLXFBConfigSGIX. This methodology, though not graceful, was choosen
as the first line of support because it could be put into 2.0 without
breaking binary compatibility.
Ultimately, Performer2.2 will have a more graceful way of supporting
pbuffers.
