Here is an extremely simple procedural texture. As the value of z increases on the intersection points,
the color alternates. Notice the extreme pixelation, which can be fixed with supersampling. Download the scene and

Here are two texture-mapped triangles. A new primitive for texture mapped triangles was created, so normal
triangles didn't have extra, unused data.
