Almost there...!

centroid was originally used by CanvasRenderer, now that it computes it as needed we don't need the bloat anymore.

Very much work-in-progress. This is going to take a while. Besides export being tedious by itself, I keep finding many things elsewhere in the codebase that need to be changed or fixed for something like this to work at all.

(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).

WebGLRenderer antialias is off by default (considering Firefox doesn't support it...)
Formatting clean up here and there

Not tested yet, as the rest of the engine doesn't work yet.

Added geometries example (need to add Lathe one).
Fixed Cylinder.

WebGLRenderer: renamed geometryChunks to geometryGroups :P

Refactored everything to use CamelCase naming for properties. Plus some smaller fixes here and there.

Went through all examples, all should work.

JSON files exported from Blender / converted from OBJ files still use underscored property names internally. I don't know, should these also be changed?

The most tangible practical effect is that demos with multiple Lucys / Walts are now initialized much faster ;).

Reuse is achieved mostly by moving mesh chunks / VBOs (formerly called materialFaceGroups) from Mesh into Geometry.

This means sorting of geometry by face materials + breaking large geometries into chunks now has to be done after construction of geometry.

It becomes a step in the usual sequence:

    geometry.computeNormals();
    geometry.computeCentroids();
    geometry.sortFacesByMaterial();

If geometry is constructed programmatically (e.g. with GeometryUtils.merge), this has to be called afterwards.

Also of note: single geometry cannot be reused both for flat and smooth shading, as only one stream of normals is baked into VBO.
