[Papervision3D] 2D coordinate to Plane 3D coordinate

[Carlos Ulloa]

I don't think you can obtain xyz from just xy. There could be more than one
point, in fact probably infinite points, that would be projected in the same
screen xy.

Your best option here would be to use MovieScene and have a separate object
in the root of the scene for each interactive element (buttons I think).

Would be good to be able to have separate containers for objects inside a
hierarchy, but that's currently not implemented.
