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