  31     INPUTS
  32         rp            - RastPort
  33         xstart,ystart - coordinate
  34         width         - count of pixels to read (must be positive).
  35         array         - array for storing of the pen numbers. Size must be
  36                         at least ((width+15)>>4)<<4 bytes.
  37         tempRP        - see ReadPixelArray8().

  39     RESULT
  40         Number of pixels read.
  41
  42     NOTES
  43         This function doesn't make sense on true-/hicolor rastports.
