[Cuis] Question on Morph instance

Hi folks,
One quick question: when a Morph is instantiated: Morph new openInWorld

The "location" ivar is assigned a MatrixTransform2x3 identity.
With
a13 being  x position
a23 being  y position

now, 
a11 or a22 must be the scale

and the rest are degrees, and?

Also, I'm a little puzzled if I inspect the morph created I get a matrix
that is [ [1.0 0.0 0.0] [0.0 1.0 0.0] ], but non-square matrices do not have
an identity matrix. Am I wrong or missing something?
thanks in advance
Nacho
