Return a reduced composition of newTransform = this(right()), or nullptr if it cannot be reduced.
"Reduced" in this context means that they are capable of being merged into a single transform, for example, for two polynomials:
\[ f(x) = 1 + x^2, g(x) = -1 + 3x \]
we would have h = f.composeAndReduce(g) == 2 - 6x + 9x^2
.
To be overloaded by derived classes if they can properly reduce the composition.

Computes the local Derivative of a transform, w.r.t.
the Derivative is represented by a AstrometryTransformLinear, in which (hopefully), the offset terms are zero.

Step is used for numerical derivation.
Derivative should transform a vector of offsets into a vector of offsets.

virtual |
fits a transform to a std::list of Point pairs (p1,p2, the Point fields in StarMatch).
After the fit this(p1) yields approximately p2. The returned value is the sum of squared residuals. If you want to fit a partial transform (e.g. such that this(T1(p1)) = T2(p2), use StarMatchList::applyTransform beforehand.
