Subject: [PATCH] Optimized postprocessing example.

No need to use full-screen render targets for quarter-screen images (still keeping big one for geometry pass to emulate antialiasing).

Also added check for existence of normalMatrix in shader when setting uniforms in WebGLRenderer. Null was being sent to GPU for materials that don't use normals (e.g particles).
