Detailed Description
Callback class to update the state of the projection, view, transform and normal matrices of a GLSLProgram or fixed function pipeline.
By default it updates the GL_PROJECTION and GL_MODELVIEW matrices. If GLSL is used and any of vl_ModelViewMatrix, vl_ProjectionMatrix, vl_ModelViewProjectionMatrix or vl_NormalMatrix is used, then no legacy uniform matrix is updated (GL_MODELVIEW, gl_ModelViewMatrix etc.) but only the vl_* ones. Reimplement the updateMatrices() method to update any other camera/transform matrix you might need such as the ones defined in http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.10.59.pdf pag 45.
