[Papervision3D] Patches for transparent clickthrough materials

[jash]

Hello,

my project is an isometric view of some space where all the stuff which is
placed in this space is rendered previously in an 3d modelling software and
the resulting bitmaps then are displayed on vertical planes. so for example
if you place a christmas tree in front of a cabinet or something, there will
be much transparent pixels at the top of the christmas tree where you can
see the cabinet behind but not click the cabinet because the event is thrown
by the transparent pixels of the christmas tree material. I can't make the
christmas tree not interactive, because it should be clickable and also the
cabinet should be clickable. the problem is even worse if there is a small
object completely behind the transparent parts of the object in front. You
can see it, but never select it.

I attached a little graphics, so the problem is more obvious.
