WebGL Vector Layer wrapX support

[pedrolopes10]

Hi guys, as in a merged pull request that WebGLPointsLayer wrapX support would be nice to have the same using WebGL Vector Layer.

Example:

Thanks

It should be supported already, but it looks like there is a bug: the layer is rendered again on the right but not on the left.
