ProjectiveTransform2D changes for revisions 27153:27154

Deleting this contribution and rewriting it can only result in the same starting point. This is the smallest possible implementation of a two-dimensional ProjectiveTransform. There is no way to do the minimalist version otherwise, except for Javadoc and the public modifier of constructor.

This contribution has been redone as below:

• Create a new class for a 2D transform using the same naming convention than all other classes in this package, namely "BaseClassName + 2D".
• Extend the base class, namely ProjectiveTransform.
• The compiler complains that there is no default constructor to inherit from the parent class. Fix the compiler error by adding a constructor with the same parameter than the parent constructor, and just pass that parameter to the parent class constructor.
• Implement MathTransform2D, which is the whole purpose of this class.

And we are done (ignoring all abstract methods that we need to implement). However while this contribution has been trivially be redone, we nevertheless keep the original author name for credit.
