virtuals for forward and reverse transforms
These routines are responsible for throwing exceptions if the 'point' arg is outside the domain of the transform.
Implements lsst::afw::geom::XYTransform.

linearized forward and reversed transforms
These are virtual but not pure virtual; there is a default implementation which calls forwardTransform() or reverseTransform() and takes finite differences with step size equal to one.
The following should always be satisfied for an arbitrary Point2D p (and analogously for the reverse transform) this->forwardTransform(p) == this->linearizeForwardTransform(p)(p);
