Also, removed webgl_trackballcamera_earth as there is already a example showing the usage and another one using this scene.

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

@alteredq: I'll try to tackle Minecraft AO next.

See #2623.

Without CubeGeometry is a little bit easier to follow. Wasn't sure whether doing it like this or using a single material/texture with modified UVs per side.
Also, I've had to comment out some code from GeometryUtils that asumed object2 to be a mesh.

This way the panel illustrates the API better.
It's not too intuitive but eventually the (future) helper will probably make it uneeded.

Ok, lets go with blue.

Still not happy about it, need more time to see what the right style for all this is.

I wonder what to do about geometries and materials used by removed objects. Seems like we would need to implement some reference counting scheme (we can't just remove deleted object subcomponents as they could be shared).

Also nicer whitespace formatting for lights and cameras in strings generated by SceneExporter.

See #2628 and #2623

Bumped scene format version to 3.2

Modified correspondingly SceneLoader, SceneExporter, Blender scene exporter and example scene files.

See #2628

I kinda got used to this behaviour from the htmleditor.

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.
