Plus added "onUpdate" callback handling also for cube textures.

Updated Closure compiler. Added more verbose compile warnings. Fixed all compile warnings. Started to fix runtime warnings in examples.

For verbose compile warnings to be practical I had to add externs and disable some warnings manually (there were tons of complains about "global this" and "cannot instantiate non-constructor"). Other solution would be to annotate explicitly constructors all over the code base.

(prompted by John Carmack's praise of static code analysis http://altdevblogaday.com/2011/12/24/static-code-analysis/)

With a little twist - per color component mixing of regular and wrap-around lightings.

As per @toji's "don't lie to WebGL about your format" recommendations in WebGL Camp 4 talk (http://media.tojicode.com/webglCamp4/#19).

Work in progress. For the moment works just with CTMLoader. Still not sure where some pieces of code would go.

Upsides:
	- initialization time cut down significantly (1.8 seconds => 0.7 seconds for CTM example)
	- much smaller GL buffers thanks to fully used indexing (Walt has 6x less vertices)
	- consequently much smaller memory footprint all around, both for main and GPU memories,
	  which means less swapping and better vertex caching

Downsides:
	- can't have anymore sharp per-face effects like flat shading (at least if mesh is not constructed in a way where each face has own vertices)
	- can't have multiple materials per mesh
	- no more easy manipulation of anything (for the moment actually no runtime manipulation at all, typed arrays are just thrown away, dynamic geometries code path not yet implemented)

As per Giles recommendation here http://learningwebgl.com/blog/?p=4379

Doing normalization of normals / binormals / tangents in fragment shader instead of vertex shader. This seems to help with artefacts appearing in certain models with OpenGL rendering backend.

Also added modulating environment reflection by specular map.

Implemented again @ekitson's improvement to GeometyUrils.center. Increased light intensity in loader_json_blender example.

Turns out it may be useful after all, seems some GPUs may have troubles dealing with texture coordinates outside of <0,1> (need to be tested if normalization helps there).

This should allow attaching of lights to objects. As a side effect, directional lights positions don't need to be normalized explicitly anymore.

Also changed viewport dimensions passed to render plugins to work with render targets with different dimensions than the screen framebuffer.

And fixed new dependencies in build script.

Also some bugfixes in ShadowMapPlugin and SpritePlugin.

Hope so. There is now just a single scene graph update per frame render (plus some extra one-shot updates if light cameras are auto-added to scene graph).

Also fixed RTT example - seems UV mapping for SphereGeometry is now rotated 180 degrees.

Too much caching can break things.

Now uses Face4 where posible.
Adde phiStart, phiLenght, thetaStart and thetaLength as extra parameters (useful for doing google-earth-like stuff).

Proper IcosahedronGeometry next...

It makes the whole thing imprecise, but cubes are now properly reflective.

And still readable code...

It's enough to clone just for hits, no need to do it for every face.
