+1 looks like a very nice feature.

I don't suppose this would help with stabilizing image colors in the 
ka-map tile generation when one uses:

   OUTPUTFORMAT
     NAME PNG8
     DRIVER "GD/PNG"
     EXTENSION "png"
     MIMETYPE "image/png"
     IMAGEMODE RGBA
     TRANSPARENT OFF
     FORMATOPTION "QUANTIZE_FORCE=ON"
     FORMATOPTION "QUANTIZE_DITHER=OFF"
     FORMATOPTION "QUANTIZE_COLORS=256"
   END

as the output format. There is a subtle shift in the color palette from 
meta tile to metatile during the QUANTIZE step.

Not asking for a change in scope of the rfc, just wondering.
