	I'm trying to create an offscreen bitmap (In Pascal) and draw a large
PICT into it.  I've done this before and everything works properly.  I
copybits things from the offscreen bitmap to the screen to do drawing,
etc.  Anyway, now I'd like to have an offscreen bitmap that is larger
than the size of my window.  It seems that my PICT is getting clipped
(?) to the size of the window.  When I do a Copybits from offscreen to
the screen everything comes out ok except for when I copy from a part of
the PICT that wouldn't have fit in the window.  (Maybe the PICT is
getting clipped to the visrgn of the window?)
	I must be doing something wrong.  I was wondering if someone could send
me some Pascal source code to generate an offscreen bitmap the correct
way.  An explanation of why it might have been clipping the PICT (or
whatever causes the problem) would be good too.
