MicroSplat - Triplanar UVs

The Triplanar module for MicroSplat add support for Triplanar UV coordinates.

Triplanar UVs are commonly used to combat stretching artifacts on vertical surfaces. While using Triplanar UVs requires 3 times as many texture samples, MicroSplat's unique blending options can lower the cost of this effect substantially vs. other shaders.
