All three classes are now in separate files.
Updated build script.
Fixed runaway globals.
Optimized loops ("in" should be used just for iterating over object properties, for arrays it's slow and also traversal order is not guaranteed).
Cleaned whitespace.
Bit more polished example.
Fixed inverted side faces for fish shape.

Gah, these things are pain to debug - "undefined" value in uniforms can lead to very weird behaviors.

Testing out texImage2D instead of texSubImage2D again.
@alteredq: which browsers/os didn't like this combo?

Updated misc_sound example with same functionality.

Plus some more Loader changes:

- fixed diffuse color and opacity being skipped when diffuse texture is present in JSON
- more proper handling of Phong materials (now use ambient / diffuse / specular / shininess from JSON)
- added handling of wrap / offset / repeat parameters for all textures

Fixed broken multiple lights indices in new normal map shader and changed displacement scale and bias to saner values.

Fixed broken postprocessing and Earth examples (were not yet translated to use new normal map shader).

Removed old normal map shader with custom lights.

Blender normal map support is work-in-progress:
 - for individual models normal map shader will need to be refactored to use standard scene lights
 - would be nice to handle also bump maps (a lot of Blender assets do not use "use_normal_map" flag on tangent space normal texture but instead use "use_map_normal" flag on texture slot of grayscale heightmap texture)

Also some whitespace cleanup.

"for ( var i in array )" is slower than "for ( var i = 0; i < array.length; i++ )"

Not perfect solution but better than nothing.

Added overrideMaterial property to Scene. If set, the material will be the only material used in WebGLRenderer.render(...). Set to null to disable.

Also fixed default camera buggy string in Blender scene exporter and changed lightmap parameter name in base Loader (to be consistent with other "maps").

Reverted to previous WebGLRenderer.setTexture code. Now that Chrome 12 is out, it should be working?
Commented out troublesome object-behind-camera check in Ray.js
