IMO there *is* value to knowing that the proper exception matrix is indeed an
exception rather than coincidentally the same as the default matrix. If the 5
is not the place for this, there should be a new flag for it.
It's especially important if all the 5s are removed. If so, the left-right symmetric slopes with an exception matrix of -1 0 0 0 1 0 0 0 1 will only function properly for left-right reflections because that's the only case where their exception matrix would equal the "default" matrix. ("Default" in quotes because it should probably be the mirror-plane matrix or some other term that describes what it is.)
Of course, this supports your methodology of treating every part listed in
mirror.ini as an exception regardless of whether it happens to use the
reflection matrix. ;-) But it would still fail if those true exceptions were
removed.
Thanks,
Carl
