IMHO (and that opinion is not worth a lot, I know *nothing* about matrices
at all...) we should add a matrix class to the image and remove Array2D.
As much as I know there are 3 Matrix classes: The Croquet Matrix, those
used in the physics simulation that was posted some time weeks ago, and Richard's
(from Nov 02). It would be nice to have a standard Matrix class, so maybe
someone will hack a plugin for some operations... I guess this could be
pretty fast if it uses the MIMD instructions that are available on the
current CPUs (e.g. AltiVec on G4/G5).
