Return a reduced composition of newTransfo = 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.
