.IX "Utility Functions" PEXBuildTransform2D
.LP
This function builds a 3X3 transformation matrix that scales
by the values in the scale vector about the fixed point, rotates
about Z axis using the fixed point as the center
of rotation and then translates according to translation vector,
in that order.
