This is a huge patch, including: * add a LitRenderModifier abstract base class for RenderModifiers with shadow+light * add LitRenderModifiers for all types of models * add STREAM_TEXGENTOUV1 to request generation of shadow map texcoords for models * create facilities to pass the texture matrix from the RenderModifier (fragment stage) to the ModelRenderer (vertex stage) * split ambient and diffuse terms of lighting until further down in the pipeline; this is necessary since shadowed regions receive only ambient light * small improvement in how RenderPathVertexShader scales to a greater number of vertex shaders This was SVN commit r3690.
