Misteriously when using the latest version of the lib on the project I'm working on I'm getting this error:
> Uncaught TypeError: Object [object Object] has no method 'set'
This is caused when THREE.UniformsLib.common.diffuse initialises a THREE.Color (THREE.Color.set() seems to be undefined then).
For some reason this only happens when I load Box2D before three.js. If I load it after is all good. But this fixes the problem too.

ColladaLoader: Removed positions scaled as suggested in mrdoob#3106.

Fixed bug where last group in OBJ was not added.

Merge remote-tracking branch 'maxogden/pointerlock-bugfix' into dev

Update examples/webgl_custom_attributes_particles3.html

The result for attributes.size.value[i] can be negative which in turn makes gl_PointSize negative. As an example if Math.sin(...) returns -1 then you'll get -6 as a result. The specification specifically states:"If the value written to gl_PointSize
is less than or equal to zero, results are undefined". In fact it is causing such a problem on our platform.
