Hi Andrew,
Can you provide evidence for who is spreading, supporting or enforcing
this "Standard Notation"?
Apart from that - especially when this standard appears disputable -
we can much better ensure we are 100% clear about it in docs. Look at
this wonderful Panda3d page:
http://www.panda3d.org/manual/index.php/Matrix_Representation
I rather see this approach for us!
