Curt,
Thanks, this has been very helpful. Been playing around with ssg a little bit
and trying to gleen some sort of understanding from the documentation, which
is very good but in some cases terse.
It looks like the panel graphic objects will need to all be ssgTransform nodes
so that they can

model components do when viewed too

Sure. Scaling is not a problem with plib. The classes
ssgTransform and ssgTexTrans are put in the scene graph to
control object and texture transformations of their kids.
One of the setTransform operations allows scaling.
Be careful with scaling objects though

Fat, dumb and happy. 2 out of 3 ain't bad.

This would work best if we put the panel into a different scene graph
from everything else:
setclipplanesforworld();
ssgCullAndDraw(world);
setclipplanesforpanel();
ssgCullAndDraw(panel);
Does this make sense? Setting up a seperate
There's an issue that needs group input. Currently there's a property value
called y-offset (there's also an x-offset that isn't used much) and this
parameter is used to initialize the panel position adjustment (shift F5 or
shift F6). The default is 0.
Some of the panel xmls define initial

I could be one. Can you explain generally what you mean by integrate the
panel code into the main SSG scene graph? Basically, yes I don't yet know
what you mean by main SSG scene graph.
Go to plib.sf.net and read the docs on SSG. Basically, it holds the
