Look on page 1151 of the RO2 PRMs! Basically, panes *are* entirely up to the
application to handle. The pane bit is only used:
To highlight the tool window if the pane gets input focus
To treat a pane as transparent if toggling the tool window's size
The explanation also, incidentally, remarks that care should be exercised in
choosing the order of window opening to avoid unnecessary redraws...
Looks to me, then, that a summary of your answer is "none" [*1]. (I read p1151.
Given all the other stuff you have to do, giving the main window the focus when
inside the pane is no big deal. And what does it mean, ``treating the pane as
tranparent when toggling''?)
[*1] Ie, there's no point in bothering with panes.
