Subject: Gltf model and animations exploring problems (#1635)

* Added bone binding to whole mesh and not only set vertices.
+ Also added missed setting of the animation count.
+ Removed double ; on one line

* Added more of the gltf sample models

https://github.com/KhronosGroup/glTF-Sample-Models
We need to make it working for all of them.

* Binding to initial bind pose added.

* Fix cube disappearing bug because lerpPercent could be Inf.

* Fixed for rigged figure also
