[Papervision3D] Detect Mouse Events in a viewport

[Steve D]

A Flash displayobject wont detect mouse events on any part of it that is
100% transparent.  The typical way to get around this is to put the mouse
event on the scene, and then manually figure out if the mouse event should
be affecting the transparent displayobject.
