Projection and Modelview Matrices

	Hello to all

	I want to do View Frustum Culling using Octrees, and everything is 
working except for one small detail: I cannot find a way to access the 
Projection Matrix, nor the Modelview matrix, which are taken for 
granted in the C/C++ versions of the library.
	Am I missing something? I can of course calculate the clipping planes 
using lookat information and the arguments to the frustum function, but 
cannot believe there isn't a more elegant solution... ;-)

	Thanks in advance, Guilherme Lopes.
