Mark,

Thank you for your comments and pointers. My reason for considering GLUT
is more for handling X events than for window management. When looking for
examples in the Performer heirarchy I find, as an example, trackball.c
(in /usr/share/Performer/src/pguide/libpfui). This is working down at the
Xevent level. While this has certain advantages, I was looking at GLUT as
a way of using someone else's (yours) investment of time and expertise
to get all of this right.

If GLUT will interfere with any of Performer's multiprocessing features, it
won't be acceptable. Does anyone know of possible interference?

Thanks, again,
Erik
