Well, yeah. But it's simpler to process it all -- the only exceptional
processing you need is "look for the part in mirror.ini. If not found, use the
default settings".
With your method, you have to also add "if the matrix looks like MD, then
process with method_a; otherwise, use method_b".
HOWEVER, you should process all parts through the mirroring operation -
otherwise, you can't handle parts at arbitrary orientations. And if you apply
just the reflection matrix (MP), you'll get reversed stud-logos in your
renderings.

Or transformation matrix, or pre-reflection matrix.
