Cause everywhere there are warnings about not writing to the same texture which is also being read. Curiously enough this didn't make problems so far (save for mysterious lines when doing "heat" effect in ro.me).

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).

Added generic ShaderPass. Removed SepiaPass, ScreenPass, VignettePass. Added bleachbypass shader. Simplified multi-composer pipeline in postprocessing example.

Added dot screen shader / effect. Extended postprocessing demo. Fixed viewport bug for render targets.

Modified examples to use it, hacking projection matrix started to feel a bit dirty.

Moved `src/materials/*Texture.js` to `src/textures/*Texture.js`

Ray.js: The bounding sphere check wasn't considering flipSided/doubleSided when the origin was inside the sphere.

extras/collada/dae.js > extras/loaders/ColladaLoader.js

removed LoaderOld.js

Some clean up on Vector* constructors.
Added UV::clone.

Work-in-progress.

I think cones are still not completely ok, but at least cylinders can be now smooth.

Still not very fond of decompose returning new array. We will see when it'll be actually used - as API allows for passing in existing translation, rotation, scale, maybe this return array could be eliminated.

Also added some comments to uniforms setter, it's starting to get a bit messy.

UV mapping for Extrude Geometry - now ExtrudeGeometry takes in 2 additional parameters, material for front/back faces, extrudeMaterial for extrusion and beveled faces
