[roll] Roll fuchsia [flatland] Fix rotation and order operations for 3D matrices.
Currently, matrices are operated in the wrong order. Translation would
be the first order of operations, and then scale. For instance, this
would mean that the translation amount would be scaled giving an
incorrect value.
Secondly, since the 2x2 submatrix rotated by 90/270 takes the following form:
0 -sin(angle)
sin(angle) 0
We, therefore, cannot scale using only the diagonal elements.
This fixes both issues.
