Although InterViews 3.1beta3 does support GL windows, it doesn't appear
that they are currently supported on the IBM.  Perhaps all you have to do
is define the correct macros in ./src/config/iv-ibm.cf that appear in
/src/config/iv-sgi.cf to get the GL support compiled in.  I don't know.

: b.	Can I combine native GL calls together with IV?  For example, can
: I use IV for menu and buttons, but double-buffering for animation etc?  How
: then would the color maps/planes be shared (because in double-buffering, I
: take over control of all the planes)?

I don't know to what level you can combine native GL calls with IV calls
(probably a lot, because the purpose of a GL window in IV is to allow GL
graphics in IV programs)

: c.	How would one make a decision between IV and Motif?

1) IV is a C++ toolkit, Motif has C binding as well as C++ bindings.
2) IV is probably more object oriented in nature.  Please, no flames, I
   don't enough about Motif to say that its definite.
3) IV glyphs are lighter weight (uses less memory) than Motif widgets
4) IV has less documentation.
5) Motif has more commercial implementations.  IV has a few, but pre-3.1.
6) Motif has no free implementations.
