Question on NSToolbar

[Fred Kiefer]

I am currently in the process of changing the GNUstep toolbar handling
to work on the window decoration view instead of using a separate view
to integrate the toolbar.

For this I need to understand a bit more of the current toolbar code and
what better way is there to do this than to rewrite that code?
Now I stumbled over the split between NSToolbar and GSToolbar. Why is
this needed or is it needed at all?
In the long run I would like to remove the window ivar on NSToolbar and
with that in place there surely is no reason for this separate super
class, but even now I cannot find any use of it in the GNUstep code
(apart from the ToolbarExample that Quentin pointed to), does it get
used outside?
