Can you try the attached?

I haven't altered the cut-and-paste code in Backend/Beagle/; anyone
who cares should probably see if the code is identical and if so
refactor.  In addition, someone who cares about pnm might want to make
read-image-file and write-image-file or write-pnm logical inverses of
each other -- I haven't tested the attached at all beyond compiling it
because I have no idea how it should be used.  Maybe if someone who
uses it attempts to document it, it will make more sense?
