[Gdal-dev] MMS false color from 16-bit unsigned data?

[Chris G. Nicholas]

I see in the MMS Raster HOW-TO "classification" section the note:

"Some format drivers (ie. GDAL) cast the pixel values to the range 0 to 255 before applying the classification scheme to them"

What's involved to address this issue; purely tweeks to mapgdal.c?  It would be extremely cool to apply these things on the fly to HDF slices and lossless jpeg2000 grayscales...
