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).

Also updated dynamic particles example to handle resizing.

There was z-fighting and obsolete UVs hacking.

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.

Not sure yet about names and location of files.

For clarity reasons I'll start setting the REVISION to *NEXT*dev for the dev branch. And updating to *NEXT* when merged to master.

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.

Fixes lightMap bug https://github.com/mrdoob/three.js/issues/458

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

It's not perfect, tail is not really looping, but at least there is not big jump for the rest of the body.
