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

Uhm, some day it would be nice to rewrite all this Shape/Path/Curve/CurvePath code...

Sorry that you had to add it @alteredq.

More examples resizing handling. Also fixed typo in flag name and cleaned whitespace in CombinedCamera.

(Phewww!) I'm sure there are still things I missed...

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

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/)

I had to resurrect parts of old code (keeping track of scene graph changes).

Good news: performance is great, new scene graph gains compound with buffers optimizations and non-array materials refactoring. Together we gained about 15% for rotating cubes performance test (pushing max to 2650 cubes at 60 fps).

Still broken with new scene graph: lod, skinning, collisions, AnaglyphWebGLRenderer, ParallaxBarrierWebGLRenderer, multi-canvas circle example.

Do not use for anything, this is just snapshot of a test in progress. I solved quite a few issues, but many things are still clumsy and broken.

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.

CrosseyedRenderer is a hack, camera must have target :S.

Found out that CrosseyedWebGLRenderer probably wouldn't work for target-less cameras.
Something weird going on with `webgl_scene_test.html` and `webgl_scene_test_blender.html`. For some reason cubes dissapear.

I knew for loops iterating over properties were slower than numerical for loops but I didn't realize how bad it was.

Gained about 10 fps in performance test, and that was for for loop iterating over single property.

Also fixed broken examples with postprocessing.

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

Also enabled antialiasing and disabled default postprocessing.

Updated text example with normals hack to be able to use smooth shading also for unbeveled geometry.
