Expects value for colors to be like "1 2 3 name\n1 2 3 name\n...". The final value is always assumed to be the name. This will read in any number of initial numbers, then the first non-number character signals the start of the name of the color.
Implements LaxFiles::DumpUtility.

Assumes the palette is already read in. filename is ignored.
If what==LAX_GIMP_PALETTE and the number of channels for the color does not equal 3, then the palette will not necessarily be readable by the Gimp, for instance, which assumes "r g b Name".
Out:
name Blah Palette columns 10 maxcolor 255 #if you say 1.0 for maxcolor, then channels are floating point in range [0..1] colors \ 0 0 0 Black 255 255 255 White 255 0 0 Red #r g b Name
If what==-1, the dump out a pseudocode mockup of the default file format.
