Detailed Description

Mesh skinning implementation.

Note

A RigGeometry may be attached directly to a Skeleton, or somewhere below a Skeleton. Note though that the RigGeometry ignores any transforms below the Skeleton, so the attachment point is not that important.

To avoid race conditions, the rig geometry needs to be double buffered. This can be done using a FrameSwitch node that has two RigGeometry children. In the future we may want to consider implementing the double buffering inside RigGeometry.
