pfPrint definately prints out colour mode: PFGS_OVERALL - or are we now
talking about a GeoSets and PFGS_POINTS? I've *never* seen PFLP_OVERALL
mentioned anywhere... Mind you pfPrint is talking about a pfLightpoint
node - not a GeoSet...

OK - I'll give that a shot. I didn't even know it was an option... More
manual page update perhaps are in order?? ;)

OK - so is this for internal use only or something? Will this code break
sometime in the future?

Is there a patch available for this? Is this fixed in Performer 2.0?
Thanx Marcus...
