Log Message:
-----------
Optimize transformSize and transformBounds, reduce allocation of Point objects.
This change addresses a couple of FIXMEs I had put in the internal MatrixUtil class. The parameters were changed to numbers instead of points and I unrolled the matrix multiplication to significantly reduce the number of multiplications and additions. Both methods now return reference to the same internal static Point object to further reduce dynamic object allocation.
