What lisp do you use it with? I agree that it looks fairly complete,
as far as it goes, and we are going to give it a serious look, but
there are a couple things we want to do with it that I'm not sure it
can handle currently:
Formatted mathematical display.
Imbedded display from another program (such as an openplot or gnuplot
window being treated as a component of the interface, even though it's
a different program.)
As a user of Garnet, do you think it could do these things, maybe with
some work to add a feature or two?
Also, it seems like it will be hard to debug if something doesn't work.
A couple of us have tried working with it in Clisp, and have run into a
few personality quirks already. I'll describe one of them for the list
in case anyone knows what is going on here - we will probably have to
deal with a lot of this kind of stuff before garnet works on gcl.
Here's what I did (remember this is clisp, not gcl yet)
and then I tried to run the 3D demo. The result was this:
*** - FUNCALL: argument (LAMBDA NIL (GVL :OBJ-OVER)) is not a function.
To get a function in the current environment, write (FUNCTION ...).

Does anyone know what's going on here?
One last point. There appear to be two ways to make garnet work on
Windows - impliment native calls to Windows graphic elements, or use
libw11 from sourceforge. Does anyone have insights on this - how hard
it would be, what pieces would be needed, etc.? (Also if we do get it
working on Windows, we would need to impliment a Windows look rather
than the Motif look.)
