 EasyScrolly - A Delphi Games Creator Demo Program - Jeff Kurtz
 --------------------------------------------------------------------------
 This little program demonstrates the use of the Copy method added to DGC.
 It will allow you to copy a region from one surface to another. Along with
 Copy is ClipCopy which has the same functionality but will clip the region
 to avoid bounds errors.

 If you know that you don't need to use clipping, use the plain Copy method,
 it should me faster since it doesn't need to do clipping calculations. But,
 if your copies are going to move off the edges of your main display surface,
 you should use ClipCopy.
