   3: /* put.c	Perform a raster operation with a source bitmap
   4:  *
   5:  *	PixmapPut	Puts a pixmap up on the screen
   6:  *	PixmapBitsPut	Puts a pixmap up on the screen
   7:  *	BitmapBitsPut	Puts a pixmap up on the screen
   8:  *
   9:  * Modification History:
  10:  *
  11:  *   Carver 8601.13 Added extern statement for SSmap
  12:  *
  13:  *   Carver 8601.06 Added line to PixmapPut to adjust the func to compensate
  14:  *		    for the reverse flag being set in the pixmap descriptor.
  15:  *
  16:  *   Carver 8510.10 Put in support for source bitmap/sub-bitmap mask
  17:  *		    copy areas.
  18:  *
  19:  *   Carver 8510.09 In PixmapBitsPut fixed the table lookup on foreground
  20:  *		    and background.
