We want to do some simple animation in Windows.  If anyone has some
pointers on this I would appreciate them.

One way we are considering is to prepare several bitmapped objects and
bitblt them (using BITBLT) to a complicated bitmapped background.  The
problem as I perceive it is how to specify the part of the bitmap you
want copied to the screen.  For example, lets say you have a donut
picture and want to send it to the screen.  The bitmap of the donut is
rectangular but the object is circular and it has an interior circle
that also must show the background.  Is there some secret transparent
color that one can use to construct the bitmap?  Or?

-thanks, david
