Ah, right, Tim brought that up. The solution to that is to create a
subclass of Panel -- like MouseToolbar is, and EditingToolbar will be --
and use that as a control. So, you have:
deactivate on these can probably even be implemented on the Panel super
class -- deactivate simply iterates through this.controls and turns them
all off, and subclasses can then change display properties appropriately.
So, I've just done that -- now anything that subclasses off panel can
be used as a 'tool' in a panel. When panels are deactivated, they
dissappear, and their buttons no longer have any affect: all the
controls on them are turned off. In the process, I also added support
for a defaultControl option. That's committed as 2629.
