[pmiess]

Add gnuwin32 package of urt.

urt has the following known problems

• rletoalias crashes
• rletogif only handles single channel images

Urt in turn depends on netpbm

the following gnuwin32 packages depend on netpbm

• groff
• palm-imgvtopgm
• palm-pbitmtopbm
• palm-ppmtotbmp
• pngutils

netpbm has the following known problems

• pcdovtoppm depends on hpcdtoppm and tempfile
• pnmindex depends on tempfile if title set
• manweb expects to be able to fall back to man
• manweb.conf cant take paths with drive letters
• manweb.conf requires absolute paths
• pamtodjvurle always oom's

netpbm in turn depends on nawk and jbigkit

nawk is an optional dependency and should it be added in the indicated location it will be picked up.

jbigkit is also a common package with 131 packages in 101 repositories on repology

These feeds depends on #97 , #87 , and #86

This PR adds the files fax2png.png and fax2png.ico which don't seem to referenced by any of the included feeds. Are they required?

[pmiess]

fax2png is the icon for the entry point for the fax2png command which is part of the tiff feed in #85 and is only here because this pull request is based on that branch.
Once that feed is merged the changes in this feed will un-comment the jpeg feed commands that depend on it.
Other than that the jpeg and tiff feeds will be unchanged from the other pull request.
