Official comment from VM guy is that it isn't needed.

Still waiting for an "official" recommendation from a VM guy though.

Also moved some more ui.js styles to the app's css.

I tried to replace the box.js with CubeGeometry but I guess material.side is still not implemented.

WebGLDeferredRenderer: made attenuation parameters properties of AreaLight instead of hardcoded constants.

Up vector can go outside of the shader. Attenuation can be computed only for lit pixels.

Also removed magic 1.5 constant in diffuse term.

Using original ArKano22's way:

http://www.gamedev.net/topic/552315-glsl-area-light-implementation/

Also added forgotten AreaLight.js

Moved computation of view space position, normal and right vectors out of shader into JS and passing them as per-light uniforms.

To be continued ...

todo:
- optimize vectors that don't need to be computed in shaders
- use material albedo
- add specular term
- wrapAround lighting (if possible)
- make attenuation parameters uniforms or defines instead of hardcoding them
- this is not using surface normal anywhere, this can't be right?
- maybe some box proxy instead of full-screen quad

add Array storage as another alternative to the Vector3 storage benchmark.  fix bug in Float32Array length method.

use switch statements in Vector2/3/4.getComponents()/setComponents() based on it being 5-10x faster than index-to-name based on benchmark_vector3components.html

inline Vector2/3/4/Quaternion.length()/lengthSq() and optimize Vector2/3/4.setLength() with unit test coverage.

See #2803

And this should be it. Probably our longest standing bug. Relief ;)
