Doesn't seem to be so when testing controlselection.pp, DrawGrabbers... 
FillRect is passed the screen-relative points of the grabber handle 
instead of client-origin. But this may be a problem in DC.FormOrigin 
instead... I removed in my local copy the Diff subtraction from the 
grabbers.left,top and then it was drawn at the correct location on win32.

Returns the current drawing origin within the current device context. So 
drawing a pixel at 10,15 with origin of 15,20 will draw a pixel at 25,35.
