Comment:
I forgot the commit message in trac_13189_cone_isomorphism.patch, no
actual code changes.
The reviewer patch looks good to me.
The virtual ray choice doesn't change whether or not there is a
isomorphism of two cones / two fans (barring any bugs), but the matrix
entries of the lattice map of course differ.
