For the moment using just fixed predefined tessellations. I wonder what UI would be good for choosing this.

Todo: better naming scheme for newly created objects.

This is to make it look better when Viewport clear color is close to UI chrome colors.

Editor: added warning when trying to export geometry for objects without geometry (lights, cameras, etc).

Default scene on the initialization is now created via resetScene action, in the same way like via menubar.

Testing the impact of normalization of transformed normals in vertex shaders (phong, normal, normalmap, skin simple).

It seems the effects on performance are minimal: in several random examples it's either not measurable, or just a tiny bit worse.

See #2613

Fixed implications of new MeshFaceMaterial.materials at multiple places (Ray, Projector, ShadowMapPlugin, DepthPassPlugin).

Thanks to @WestLangley for vigilance (see #2623).

Patch to #2623

I believe this is not needed anymore.

Also for the moment in depth pass skipping all ParticleSystems without custom depth material. Otherwise there are GL errors, need to create a proper generic depth material for particles.

See discussion at https://github.com/alteredq/three.js/commit/5cb715520806a5afa1057a31a6777c2e454eeff0

This is necessary for OpenGL where pow(0,0) is undefined and can be negative (in DirectX you just get zero), leading to negative light creating black areas artefacts.

Fixes #1805 and #2615 (related already fixed #998).

See discussion in #2613

Finally I just left it behind a flag. I was not able to get as good results for TextGeometry as with unweighted method and split materials for side and front faces.

I wonder how I got that nice look as in screenshot I posted in the issue. It still does look better with weighted than unweighted but nowhere so close as in that screenshot. Either I did some mistake when testing before or there is some bug in implementation now.

See #2610

Small fix to #2610

Because that's what it is.

Now it should look the same no matter where the object is located.
