The SoModelMatrixElement class is used to manage the current transformation.
SoModelMatrixElement contains the object-to-world matrix.
The world-to-camera transformation is stored in the SoViewingMatrixElement class.
Note that one thing that can be a little confusing with the API is that SoModelMatrixElement does not contain the same matrix as the OpenGL GL_MODELVIEW
matrix.

This function returns TRUE
is the element matches another element (of the same class), with respect to cache validity.
If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.
Reimplemented from SoAccumulatedElement.
