First off, thank you for packaging ploticus.

IMO, the testsuite can definitely be omitted.  The samples could be useful
(in /usr/share/ploticus*).

I would suggest just creating separate fonts package(s?), if you can
figure out where the fonts come from...

Yes, it's a filename clash -- we had those before.  The solution would be
for *both* packages to provide a uniquely-named executable and a
postinstall script that would create a symlink.  Then the nature of
/usr/bin/pl would depend on the order of package installation (actually,
the order of postinstall script execution).

Well, it wouldn't in a sense that you'd have both /usr/bin/pl and
/usr/bin/pl.exe (the latter will shadow the former).  But you'd definitely
need to coordinate with the maintainer of SWI-Prolog (Corinna?) to add
those postinstall scripts together.
