There's a kids-packing rule for the frame widgets but it doesn't know
about visible or collapsed slots.  In fact, I'm pretty sure celtk
doesn't know anything about these.  The only reference I could find to
either was in the gui-geometry bit of cells which doesn't seem to be
used by celtk.  Grepping through Celtk for either "visible" or
"collapse" yields nothing.  Maybe this is another celloism?

I was thinking about this though as a further change.  We could add a
visible slot to tk-object and the kids-packing rule could check it
while creating its pack statement.  I'll get the expander finished
first though.  Just need to draw the bitmaps on the buttons.

Thanks for all your help.
