ColladaLoader, checking if responseXML exist before parsing it. Removed ?rnd= bit, not sure why that was there...

ColladaLoader tried to access children-less object childrens. Changend JSONLoader try/catch code (better error logs this way).

Fixed bug caused by incorrect use of Matrix4.decompose(). Also fixed bug in Animation - reference to deprecated Object3D.update() function.

Removed unnecessary vertex hashing which caused bugs if geometry was small enough for the hash function's rounding to cause loss of precision. Added support for faces with vcount greater than 4 by subdividing. Fixed texture bugs: V for UV was inverted, UVs not set for Face4s, offset and repeat and wrap options not set properly.

Removed the unused initial xml doc creation that happens automatically from the XHR which returns an XML DOM object.

Changed console error to return null and updated WebGLRenderer to handle null value. A valid matrix with no rotation and 0 scale will have a 0  determinant and does not need a normal matrix.

Fixed typos in Matrix4's transpose() and getInverse(). Also added convenience functions for adding a translation or rotation to a matrix (rather than just setting them).

Bad things (and hard to debug) can happen that affect Ray.

This creates shallow copy of object and its children (geometry and materials are shared, transforms are unique).

Added link to library build instructions

Hope so. There is now just a single scene graph update per frame render (plus some extra one-shot updates if light cameras are auto-added to scene graph).

No time right now to re-create the examples using Ray. Will do for r47...

Also fixed RTT example - seems UV mapping for SphereGeometry is now rotated 180 degrees.

Too much caching can break things.
