Detailed Description

Overrides the virtual methods on SoModelMatrixElement to send the matrix to GL when necessary.

Note that this class relies on SoModelMatrixElement to store the matrix in the instance. This is less expensive in the long run than asking GL for the matrix when it is needed.

Because GL stores the model and view matrices in one matrix, this has to do a little extra work when setting the model matrix to identity or another matrix. (It has to set the GL model-view matrix correctly.)
