[Bf-committers] Change Representation and Initialisation of Matrices to Conform with Standard Notation

Hi All,

I have written a patch which rectifies a cause of confusion among Blender
uses when starting out with matrices and vectors. The patch ensures
consistency between the matrix representation and matrix/vector products so
that they behave in the way that people familiar with math expect. This is
achieved by adjusting pythons access to the internal storage, while keeping
the internal data the same. Note that this does not interfere with how
matrices are stored internally or how matrix products, additions etc are
performed internally.

The patch can be found here:
with a more in depth explanation.
