Hi there,
I've got a couple of questions.

* For indexed pfGeoSets, is it a problem to have attributes in the
attribute list that are not referenced by the index list? An example:
several pfGeoSets using a master list of vertices but constructing
different polygons from it.

* I'd like to construct a pfGeoSet with the attribute data sitting in
one pfMalloc'ed block of memory instead of seperately pfMalloc'ed
lists for each attribute. If one of the attribute lists begins at the
head of the pfMalloc'ed block, will the reference counting mechanism
become inconsistant (e.g., another pfGeoSet is not sharing that first
attribute list, but might share others, like in my first question)?

* I'd really, really like to hang out in select () and process I/O
events rather than block in pfSync (). Is it possible to get access
to the signalling mechanism used to implement pfSync ()? I could
implement my own signalling between the draw and app processes, but
that seems kind of redundant.

Tim
