FILLPATTERN         Fill Graphic Rectangle With Pattern              pp 175

 Syntax:  FillPattern (X1,Y1,X2,Y2,Color) ;

 Type:    Integer

 Form:    Extended Graphics Procedure

 Purpose: Fill graphic rectangle with Pattern.

 Notes:   Requires {$I Graph.P} include file in the source file.
          The rectangular graphic shape delineated by the corner coordinates
          of X1,Y1 and X2,Y2 is filled with the pattern defined by the
          Pattern statement.  Color 0..3 is selected from the color
          palette.  0 bits in the pattern cause no change to the display
          whereas 1 bits cause a dot to be written in the selected color.
