* Internal atom that copies an appearance on to the blocker plane

* Copies an appearance vis render_target and render_source on to the emissive blocking plane.
|
|
* This means that the atom in question will block any emissive sprites.
|
|
* This should only be used internally. If you are directly creating more of these, you're
