[sldev] Various questions on the viewer.

[Kent Quirk (Q Linden)]

Jason:

I don't (yet) know the answers to your questions, but I can tell you 
that starting next week, I'm going to be working on a project (along 
with a couple of other people) called "User Interface Cleanup" that 
includes, among other things, a reworking of the way we handle callbacks 
and a reorganization of XUI. We expect to spend most of the next quarter 
on it.

SL grew a bit more organically than any of us would like -- but now 
we're trying to apply some good engineering principles. So hang in there 
and we'll keep you posted.
