Skeleton updated outside of frustum

[ashconnell]

Description

In WebGLRenderer.projectObject(), SkinnedMesh is left out of the frustum check directly below it.

I tested moving this inside of the frustum check and saw a large performance increase for scenes with a lot of skinned meshes with no noticable issues.

Does anyone know if this is intentionally left out of the frustum check?
And would you accept a PR to improve this if there are no side effects?

Updating the skeleton only when the skinned mesh is inside the view frustum sounds like a good idea. The method only updates the bones texture which isn't required when the object isn't rendered at all.

And would you accept a PR to improve this if there are no side effects?

A PR would be highly appreciated! 😇
