Default value is THREE.BackSide (use backfaces of objects when rendering depth map), other valid value is THREE.FrontSide (use frontfaces of objects when rendering depth map).

Specular parameters will eventually need to go into G-buffer.

Started with extraction of deferred shading code snippets into more reusable components.

Before base class attributes that weren't in the constructors were not cloned properly in derived classes.

This is needed for handling manually created non-power-of-2 or small RGB DataTextures.

It corresponds to GL_UNPACK_ALIGNMENT parameter in glPixelStorei:

http://www.khronos.org/opengles/sdk/docs/man/xhtml/glPixelStorei.xml

Warning: this doesn't work with RGB textures (3 bytes per pixel) because of default 4 byte alignment requirement deeper in WebGL / OpenGL layer. Uploading smaller mipmap levels gets these GL errors:

"ArrayBufferView not big enough for request with UNPACK_ALIGNMENT > 1"

It works ok with RGBA textures (4 bytes per pixel). Seems this could also explain why 1 pixel RGB DataTextures were failing sometimes.

@sole you might be interested in the script i used to help generate this.

p = new THREE.Path()
for (i in p) {
p.hasOwnProperty(i) && console.log('\n<h3>.' + i + '</h3>');
}

console.log('-------------')

for (i in p) {
var pp = p[i].toString().replace(/function/,'');
THREE.Path.prototype.hasOwnProperty(i) &&
console.log('\n<h3>.' + i + pp.substring(0, pp.indexOf('{')-1).replace(/\s+/g, ' ')  + '</h3>\n<div>todo</div>' );
}

Right now, if the DDS data is a cubemap, the code is hardcoded to load 6 faces. This could be made more robust by checking DDSCAPS2_CUBEMAP_POSITIVEX, etc. to verify that all 6 faces exist before reading the data from the buffer.
I also did a quick update of the webgl_materials_texture_compressed example to load a cube DDS.

Now morph buffers behave the same like other buffers and do not attempt to get set when materials do not use corresponding attributes. Not having this was crashing deferred rendering when shuffling around materials in G-buffer passes.

fixes #2666

Gained more performance, used it for more bling.

Up to 95 fps.

Small performance improvement (88 fps => 91 fps).

Much faster with "discard" (56 fps => 88 fps).

Also fixed light colors to be in linear color space to match the rest of the pipeline.

- changed model to Lee Perry
- changed light pass material to use RGB-weighted wrap-around lighting (with deferred can't have easily together multiple material types :S)
- changed deferred rendering to use linear space lighting

Refactored deferred rendering example to make it easier to use per-object depth and normal materials.

This is to make it work with textured objects that use Geometry (instead of BufferGeometry). Otherwise reusing the same Geometry between color and normal passes creates buffer requirements clash, where one pass needs just normals and other just UVs.

ShaderMaterial forces creation of normal and uv buffers all the time (MeshBasicMaterial just creates what's needed for the first render).
