There is a bug of Viewport.unbind?

[chengenzhao]

Hi:

The implementation of viewport.unbind seems like a bug
cause it only unbind the zoom property
if we bind the viewport to an entity and then unbind it and also set the x property then it won't work
like:

viewport.bindToEntity(player);
viewport.unbind();
viewport.setX(1000);//it doesn't work

and I checked the source code the proper way of real unbind should be:

viewport.bindToEntity(player);//bound
viewport.bindToEntity(viewport.getCamera(),0,0);//unbound
viewport.getCamera().setX(1000);

so is it a bug of the code?

Thanks
