[x3d-public] x3dom HAnim with skin testing ideas

This is a request for testing ideas and general feedback for a first
rudimentary but fairly functional x3dom HAnim with skinned animation

Here is a test page:


I collected known HAnim examples which more or less work now.

The Displacer node is not implemented yet.

The skin deformation is all done on the CPU (with js) and is therefore
slow generating lots of js objects. The mesh is reconstructed for each
affected geometry from scratch for each frame. Only geometries with a
'coord' field are visually updated but most (all?) indexed ones have
the vertices in such a field.

For simple geometries the performance may be acceptable but the main
purpose at the moment is to have functional code which can then be
optimized. On the other hand, I only have a fuzzy idea how to involve
a shader.

Any feedback appreciated,
