This buffers scene item visibility actions so that if obs_sceneitem_set_visible to true or false, that it will ensure that the action is mapped to the exact sample point time in which obs_sceneitem_set_visible is called. Mapping to the exact sample point isn't necessary, but it's a nice thing to have.
