Yes!

FYI, Performer also allows you to directly pass in GL_* tokens for
internal format so you are not limited by the PFTEX_* list.

What is special about the PFTEX_* tokens is that if any corner cases
arise with them (such as not being supported on some machines) we
will handle them gracefully (ie. choose another close match).
