[Usability] Limiting window maximization

[Richard Gaskin <ambassador fourthworld com>]

When I click the maximize control in the window's title bar, the window 
expands to fill the region defined by the display less any panels and docks.

This is great for most apps, but I have an application which has a 
floating toolbar separate from other windows, and I'd like to be able to 
limit the maximize bounds of those windows to a region clipped below the 
bottom of the toolbar, to avoid having those windows' title bar 
submarine beneath the toolbar.

I understand that for most apps it would be a better idea to simply put 
the toolbar into the top of the window, but this particular app has 
multiple windows for various views and it's been problematic to come up 
with a single-window/multi-pane layout that gives our users the 
flexibility with how they arrange their views as they currently enjoy by 
having each view in a separate window.

So this leaves me with a toolbar detached from those windows and a need 
to limit the maximize rect for them, but I can't find an API to do that 
as there is for OS X and Windows.

Is there one that I've just overlooked, or is this something that could 
be considered for addition to the API?
