Transformation matrix interface - pre-multiply/post-multiply definitions

Hi Dirk,

I was having a look at the Matrix spec [1] and I believe the definitions for pre-multiply and post-multiply are backwards.

>From [1]:
Term B postmultiplied by term A is equal to A  B.

>From wikipedia [2]:
post-multiply (or right multiply) A by C" means AC

Using B and A, as in your text this would give
post-multiply (or right multiply) B by A" means BA

And likewise for pre-multiply.
Could you check please?
