A similar question:
I wanted to use a hollow transparent sphere to give some curvature
to my leaf image map, and it works great except when the transparent
part of the leaf's sphere intersects a (non-transparent) surface
behind it. I get black pixels, like it's showing coincident surfaces,
though the sphere's surface is transparent at that point.

I was thinking that I could use the image to clip the sphere somehow
(instead of a another sphere as I'm currently doing), but I wonder
if there is a simpler (and faster rendering) solution?
