NAME
       UStencil - structured graphic displaying a bitmap

SYNOPSIS
       #include <Unidraw/Graphic/stencil.h>

DESCRIPTION
       A  UStencil  is	a  Graphic  that displays a bitmapped image.  Two Bitmap objects, an image and a mask, define a stencil's appearance.  The
       stencil potentially paints foreground color where image has a true value and background color where image is false, but	only  pixels  that
       have  a corresponding true value in mask are thus affected.  The stencil's origin coincides with the origins of the image and mask bitmaps.
       The mask's bounding box defines the stencil's extent.

PUBLIC OPERATIONS
       UStencil(Bitmap* image, Bitmap* mask = nil, Graphic* = nil)
	      Construct a UStencil, supplying an image and an optional mask bitmap and an optional graphic from which to obtain an initial set	of
	      graphics	state.	 Specifying  nil  for mask is equivalent to supplying a mask of the same size and shape as image that contains all
	      true values.

       void GetOriginal(Bitamp*&, Bitmap*&)
	      Return the bitmap parameters supplied in the constructor.
