Re: Fix: NSWindow, setFrameFromString and stringWithSavedFrame

[Nicola Pero]

Hi Georg,

I think Richard wrote that code, and looking at the ChangeLog I suspect he
wanted it to save the top-left corner on purpose.  The fact that there are
explicit comments about using flipped coordinates is also suspicious that
there is some real intention in using them.  I just wish Richard had been
a little more verbose in the code :-) [he's away for some weeks at the
moment]

But the only advantage I can see in saving the top-left corner is if you
edit your defaults/window strings by hand.  If you edit your defaults by
hand, then of course saving the top-left corner is better, since you can
then edit by hand the size of a window, and the top-left corner remains
correctly placed (if we save the bottom-left corner, you also have to
manually adjust the window origin when you manually edit the window size).  
Is this the only reason why we save the top-left corner ?  Not a big
issue, compatibility seems more important.

I don't have an openstep system (nor a macosx) to test what actually
happens in other systems - can someone else confirm that we really need to
change the way we convert window frames into strings in order to be
compatible ?

Anyone has any help/comments on this change or can enlighten me on why we
currently save the window frame top-left corner and why changing/not
changing the way we save it ?
