ss reflections tweakage:
+ // Offset the guess source a little according to a trivial
+ // checkerboard dither function and spec.a.
+ // This is meant to be similar to sampling a blurred version
+ // of the diffuse map. LOD would be better in that regard.
+ // The goal of the blur is to soften reflections in surfaces
+ // with low shinyness, and also to disguise our lameness.
