[x3d-public] HAnim Winter and Spring: some progress

[Holger Seelig]

The problem with these models is, that several skin coordIndices are referenced up to 12 times in several HAnimJoint nodes. This is too much for a GPU accelerated humanoid. X_ITE only supports 4 references, as specified as minimum in glTF standard. This is normally enough and there are a lot of complex glTF models in the Internet, which will work.

When HAnim was implemented as a CPU, these models also worked, but most of the models consumed so much processing power that there was no real need to talk about them working.

For this reason and because it allows X3D4.0 and HAnim 2.0, I built the GPU version, with the trade-off that not all, and especially too complex models, are no longer supported.

Best regards,
Holger

> X_ITE selection very badly broken for unknown reason(s) same as default view.
