Transparent TriMesh bug

[James W. W. <ja...@wr...>]

I ran into a situation where a transparent TriMesh should be out of 
view of a camera, yet some distorted part of it is visible.  The 
object is slightly behind the camera and off to the side.  I am not 
sure that I totally understand the problem, but I found a way to make 
it go away:  Modify ir_geom_transparent_add to reject a primitive 
unless all of its z coordinates are in the correct visible range, 0 
to -1.  Comments?
