This is a separate problem which caused us lots of grief implementing 
Control.moveAbove()/moveBelow().  It's currently broken, and I just don't 
know what to do about it.

The relevant spots are UtilFuncs.setLocation()/setSize(), Control.setBounds() 
and the guys it calls, and Control.computeSize().  The basic problem is that 
widgets in SWT want to have full control of positioning, and use no help from 
GTK's layout containers like the GtkBoxes.  The GtkFixed doesn't quite leave 
the children alone, and set_uposition / set_usize don't fully work - 
uposition because you can't have a negative orogin, and usize because it 
screws up the child's notion of requisition.  We solve this by using the 
set_usize on a bin whose only function is to hold the child - the child 
expands to occupy the whole bin, so always stays the right size, and is still 
able to answer the requisition when we want to computeSize().
