new categories wanted

I've got some scripts I'd like to upload, but they don't fit
in the existing categories.

Specifically, I've got these:

pnminfo		information about a PBM/PGM/PPM file (more info
		than pnmfile will give)
pgmtoascii	like pbmtoascii, but grayscale input gives better
		output
mkthnail	assemble a PPM tool pipeline to make PPM thumbnail
		images of input files (most of the PBM/PGM/PPM
		supported formats can be input files)
mkjpg		assemble a PPM tool pipeline to make jpegs from
		PGM/PPM files
mkgif		assemble a PPM tool pipeline to make gifs from
		PBM/PGM/PPM files
mkbmp		assemble a PPM tool pipeline to make bmp from
		PBM/PGM/PPM files

Since these are all wrappers for the PBM/PGM/PPM tools
(http://www.acme.com/software/pbmplus/) some sort of recognition
of that in the category would be good. "Graphics::PNM" sound good?

Glossary:
PBM	portable bitmap (one bit per pixel images)
PGM	portable graymap (one color channel, typically 2 to 8 bits
	per pixel)
PPM	portable pixmap (three color channels, typically 1 to 8 bits
	per color)
PNM	portable anymap (any of PBM, PGM, PPM)
