Defaulting the crossOrigin attribute to 'anonymous' causes browsers to
not send credentials along with the request, even if the request is not
cross origin (at least with Chrome). A better default is to not set the
cross origin attribute, allowing browsers to behave normally. Users in a
cross origin environment can override this value.

previous was :
var fullPath = texturePath + "/" + sourceFile;
but texturePath may already have a slash (see extractUrlBase function)

changed slash to texturePath.slice(-1) === '/' : '' : '/'

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.

Also, removed GeometryLoader. I'll try doing the JSONLoader to GeometryLoader change again in the future.

Added support for compressed textures to Loader base class. Added compressed textures to JSON loader example.

Also moved "startsWith" and "trim" string shims from OBJMTLLoader into Three.js file and added "endsWith" string shim.

Downside of using compressed textures is that texture.flipY parameter doesn't work, so either textures or UVs need to be flipped somewhere else in the asset pipeline.

This is because WebGL doesn't have access to the content of compressed textures (similar to how automatic mipmaps generation doesn't work with compressed textures, so mipmaps need to be baked in DDS).

See discussion on WebGL mailing list here: https://www.khronos.org/webgl/public-mailing-list/archives/1209/msg00024.html

For the JSON loader OBJ example I just flipped images in Gimp (other option would be to keep images intact and flip UVs in the application after loading geometry).

Moved colors, bumpScale, shininess and anisotropy parameters from lightmap example code to its JSON file.

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

Still needs to be done: canvas renderer / picking / canvas examples.

Because sometimes you just need to get rid of junk stuff sneaking into asset pipeline.

I tried to move BinaryLoader to /examples/js but SceneLoader needs it.
Curious to hear what people thinks about this change.

- removed not anymore existing ro.me specific remains (triggers, mesh colliders and shadow volumes)
- added custom properties for setting shadow map casting and receiving, depthWrite, depthTest, blending, doubleSided
- using Blender native "transparency" checkbox for setting out "transparent" property
- better handling of messed up texture slots

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.

Should fix #779...
