  32 /*  FUNCTION
  33         Writes the same color value to all pixels in a rectangular region of
  34         a RastPort.
  35
  36     INPUTS
  37         rp - the RastPort to write to.
  38         destx, desty - top-lefthand corner of portion of destination RastPort
  39             to write to (in pixels).
  40         width, height - size of the affected area (in pixels).
  41         pixel - the color value to use, in 32-bit ARGB format: 1 byte per
  42             component, in the order alpha, red, green, blue.
  43
  44     RESULT
  45         count - the number of pixels filled.
