Comment (by rcurtin):
I'm sorry, I was wrong; the identity matrix isn't centered so it isn't the
right one to test. What you want to test instead is this:
1 0 0 -1 0 0
0 1 0 0 -1 0
0 0 1 0 0 -1
and that should have a result that looks something like
a 0 0 -a 0 0
0 a 0 0 -a 0
0 0 a 0 0 -a
but I haven't bothered to calculate what a should be (probably 1 or
something like that).
