Here's today's bonus patch showing how to do reflection and refraction

with shaders. The shader implements a basic Fresnel model which is

controllable via bias, scale and falloff parameters. These control

the ratio of the reflection and refraction colors based on surface

orientation to the camera. The texture lookup is done using a

sphere-map so the quality is not as good as it would be with a cube

I would love to see this shader, but the link seems dead .

Does anyone have this patch somewhere, please ?
