The big problem is that there are no single set of rules - the way things
work (row/column orders, how results should be presented etc) change
depending upon the application. You could implement "general vector
operations" or "general matrix operations" but then you have to decide
*which* general ones to implement - the ones that mathematicians prefer,
the ones used by 3D procgrammers (which are slightly different) etc.
I expect one of the reasons RT have avoided this issue is simply because
matrix maths are such a thorny area...
