Most any format out there should support transparency, the inventor loader
does, for example. (perfly windmill.iv). Performer does not know whether
a pfGeoSet has transparency in it or not, so you have to give it a hint.
The way you do this is to attach a pfGeoState to that pfGeoSet that
contains this information.
pfGeoState *g = new pfGeoState();
g->setMode(PFSTATE_TRANSPARENCY, PF_ON);
