multiplyTransposeXYZW Method

Multiply the homogeneous point by the transpose of this Transform. Return as a new Point4d or in the pre-allocated result (if result is given).

• If p = (x,y,z) then this method computes M^t*p and returns it in the first three coordinates of the Point4d, and o*p + w in the fourth.
• Logically, this is multiplication by the transpose of the 4x4 matrix formed from the 3x4 instance augmented with fourth row 0001.
