WebGLVertexArrayObject hack to replace Texture input hack?

@fuzzie360
Im not so sure on the details, but VertexArrayObject, does allow to stuff in floating point positions. Probably not at 64bit yet, but atleast something.

And apparently the only limit it has is the number of vertex limit, which is 64k elements.
Which is probably quite acceptable for our use case?

Just a wild idea
