You can not convert arbitrary math transform to a matrix. For example the
following can *not* be converted to a matrix:
* all map projections except "Equidistant Cylindrical" and "Plate Carree".
* Molodenski
* Geocentric to Ellipsoid and the converse.
* Passthrough
* And much more...
Actually it is impossible in the majority of case... However there is a few
case
where it is possible, when the transform is only:
* Unit conversion (only for linear unit)
* Axis flipping and swapping
* Dropping a few dimensions
* Scale, rotation, translation.
In such case, you can cast the MathTransform to LinearTransform and invoke the
getMatrix() method.
