FWIW, fnlib does not require libpng itself; it is, however, linked
against libpng3 thanks to the usual libtool idiocy.

If upstream is dormant (and I know that's an understatement), you could
also try to coordinate with other vendors who might still ship imlib and
agree to pick a new soname anyway.  That seems a better choice than
creating a new package that conflicts with imlib1, IMHO.

No problems here, at least.
