Matrix package

[gunnsth]

Right now all treatment of matrices is via the image.Image interface and frequently a utility function is used to convert the image.Image to an RGBA image.

Would it be useful to have an internal matrix type? The matrix could be created from an Image instance. Mathematial matrix operations could be applied to it. Matrix multiplication, Scalar multiplication, etc.

That could be very powerful for other image processing operations. Having used Matlab, Octave quite a bit in the past, I could see that this could allow some very powerful use.

For instance, being able to apply transformation matrices to images by simple matrix multiplication can be easy to use and powerful with many use cases.
