Also change use of setClearColorHex to setClearColor.

Renamed ShaderLib's 'normal2' shader to 'normalmap' as suggested in 4276c9f5.

ShaderUtils relied on ShaderChunks so this created troubles when trying to use three-canvas and three-extras. Besides, better to keep a single library of shaders.

Refactored EffectComposer, added setSize method. Changed examples with postprocessing to use setSize.

Renamed screen shader to blit.
Throwing errors in *Pass if the shader aren't available.

@alteredq: I think ShaderExtras.js is starting to become bulky and messy... What do you think about splitting ShaderExtras into single files? Contributing new shaders would then feel more welcoming. And the examples would show the dependencies clearer.

I was unsure on what style use... THREE.WebGLShaders['film'], THREE.FilmWebGLShader or THREE.FilmShader. The later seemed the nicest

Finally it was much simpler issue than I thought ;)

Use two component normalScale and set eventual flipping per-model. It's quite ugly but it could do the job if we don't find a better solution.

Do not merge yet.

See #2358

All examples should work now.

The only weird thing seems to be that for some reason bone texture doesn't like to be assigned to arbitrary texture unit (or more precisely to alternating texture units).

See #2340

Sorry that you had to add it @alteredq.

This should be the last one. The only ones left should be "webgl_postprocessing" and "webgl_postprocessing_dof" where I got stuck.

Fixed all the examples that used PlaneGeometry except webgl_terrain_dynamic.html (not sure what's going on :S).

Inverse mask effect stopped working as it depended on buggy stencil buffer being always turned on due to spelling error (which got fixed recently).

Except special cases like 3d renderers and cube cameras all examples should be now without warnings.

Lots of code got cleaner with seconds, seems we used them before all around.

Also changed examples that didn't need deltas to simple Date.now() plus some more examples cleaning, trying to get rid of obsolescence warnings.
