ProjectiveTransform changes for revisions 24924:27154

The main change is the creation of a MathTransform2D implementation for the two-dimensional case. The same pattern is applied in other classes (Identity, Molodensky, basically every transform that may have arbitrary dimension). So we can copy-paste-edit the same code from other classes. Anyway, the code is written differently in Geotk / Apache SIS (using a if statement instead than switch, but this is very minor details).
