Detailed Description

Represents a generic 3*3 matrix.

It is defined in a row-major order, it means that, in the value buffer, the entire first row is stored first, followed by the entire second row, and so on. You can access the data with the 'r' ptr or by element attribute.

r00	r01	r02
r10	r11	r12
r20	r21	r22
