quick recipe:
- use getextrema to get the min/max value for the image (unless already
known)
- use point to translate the image down to an "L" image; you can use either
a the argument*scale+offset form, or a 64k lookup table:

- use putpalette to attach a palette to the L image:

- if necessary, convert back to RGB.
