I now remember bug 16305. Mark entered it based on a list discussion 
where I reported it. Hence my comments on it. I now use Panos's 
workaround (in fact my code base is riddled with "work-arounds"), but 
there seem to be a (limited) consensus that on Windows 10, the effective 
rect should only factor in VISIBLE border elements, not INVISIBLE ones. 
I still wish they would fix it.

That all said, where is effective width/heigh/rect of a stack/window 
documented in the Dictionary? The 'effective rect' and other 'effective' 
dimension properties of a stack/window are important for multiple window 
positioning, resizing, alignment, and more and should be in teh 
Dictionary. ALSO, as the 1 exception to the "you can not SET 'effective' 
things rule, that should definitely be documented.

I'll file a documentation bug report, but I don't want to file one just 
to find out I looked under the 'wrong' place.
