I feel bad about you not getting a reply, so I want to give a reply even
though it's not a super helpful one:
Use whatever way you can come up with and that

Personally I don't see the point in duplicating a matrix lib in
every software, i.e. I question the introduction of GeglMatrix3 in
the first place, I mean there certainly must be high quality libs
for matrix operations out there, but that's a different story...

IMHO, when all you are dealing with are 3x3 matrices (which are not
arbitrary 3x3, since they represent affine + perspective

would be slower. Even more so with 2x2.
So, my

Since GeglMatrix3 exists, GeglMatrix2 also should exist for consistency.
Should GeglMatrix2 also reside within gegl-matrix.c, or should it be
separate? I can quickly create GeglMatrix2 for the purposes of passing
Jacobian
Adam:
(Ignore if my last email about GeglMatrix3 was off the mark.)
Is it that affine transformations, stored in 3x3 matrices, get
simplified when they are chained?
If so, where is the final overall 3x3 representation?
Hopefully, extracting the linear part from it to compute the inverse

In addition, I will need to expand the OpAffine struct to include an
additional GeglMatrix3 (call it matrix_inverse or inverse_jacobian?)
to store this data.
GeglMatrix3? Is this a 3x3 matrix type?
(Ignore the following if it is not.)
Maybe the matrix created by the
