There are two functions, pfuMakeTexList and pfuMakeSceneTexList that perform
that function. The difference between them is whether you pass a pfNode* or a
pfScene* to the respective functions. The code is distributed in the libpfutil
directory in the file tex.c, if you want to see how it is done.

Detail textures are not treated as seperate textures, but instead, they are
tied directly to a base texture. For this reason, you will not see them in
your texture list. If you want to know about them as well, look at the tex.c
example in the CalculateNumPage function. Down near the bottom of the
function, there is a check to see if a given texture has a detail texture
associated with it. In Performer2.2 the code for this is in tex.c. In
Performer 2.0.2 it is in tex.c.impact.
