[Bf-committers] transparent meshes rendered out of order -- bug 153

[Jonathan Dubois]

I have updated the example with non-intersecting planes and the problem is 
still present in the game engine.   Even if only the center of the plane 
is used to determine which plane is drawn first / last I dont understand 
why objects which are farther away are getting rendered in front of those 
which are closer to the camera.

the offending example is at
