New Revision: 12272

Modified:
   trunk/ghostpdl/pl/dwmainc.c
Log:
For PCL's benefit we change the display format to DISPLAY_BIGENDIAN -
RGB instead of BGR.  PCL raster operations will not work with the BGR
color model.  This does introduce byte shuffling, BGR is native, which
might make the device a bit slower.
