I'm not sure what your problem is ... but I'm guessing it's confusion  
between two different window systems.

The origin of an NSWindow (ie a window in GNUstep/Openstep/MacOS-X)  
is its bottom left corner and increasing Y-coordinates move up the  
screen.
The origin of an X window is its bottom left corner, and increasing Y  
coordinates move down the screen.

So if you resize using the bottom left corner the you have both a  
move and a resize of the NSWindow ... this is handled by the 'if  
(resize == YES)' case (which updates both size and origin).

The 'else if (move == YES)' case will only be executed if you move  
the window without resizing it ... in this case we change the origin  
but not the frame size.
