Strangeness in NSWindow

[Fred Kiefer]

While tracking down a wrong behaviour in my own backend code I found 
that this time it was not me getting things wrong but NSWindow. When 
creating a new window the content size is handed on to the backend while 
the very similar method placewindow:: takes the full frame not just the 
content area. But if this is the way we want it it is fine for me, now 
that I know it and adjusted my code to it.

Could anybody (Adam?) explain the semantic of the findwindow::::: 
method? As our only official window server does not implement it an it 
is never used from gui, we could perhaps drop it as well.

Then there is this NSWindowDepth stuff, according to NSGraphics this are 
 rather complicated values that describe the availabe colours of a 
window or screen. But in NSWindow 8 is returned as a NSWindowDepth and 
the method [windowdepth] on XGServerWindow also returns rather just a 
bit size. So what is the use of all this and what would be the correct 
beahviour.
