#   OffSample demonstrates the usage of the Offscreen

#   unit. It shows how to use offscreen pixmaps and

#   bitmaps to produce flicker-free updating with a

#   minimum of re-structuring of code. OffSample attempts

#   to reduce the amount of 'knowledge' that it has of

#   the offscreen structure so as to minimize its

#   dependence on that unit.

#

#   OffSample emphasizes using the Offscreen unit; it

#   is not intended to be viewed as a complete application

#   from which to base some larger effort. Instead, its

#   method of using offscreen bitmaps and pixmaps should

#   be studied and adapted to other applications that

#   desire features such as flicker-free updating.
