SoDecomposeMatrix — decomposes transformation matrices into values for translation, rotation, and scale

Description

       This  engine  takes as input a transformation matrix and a center of transformation. As output the engine
       produces the translation, rotation and scale values derived from the matrix.

       The input fields can have multiple values, allowing the engine to decompose several matrices in parallel.
       One of the inputs may have more values than the other. In that case, the last value of the shorter  input
       will be repeated as necessary.
