TransparentShadowCaster

Description
Handles transparency and takes it into account for casting shadows.

Usage
Modulate the "_Cutoff" variable to get a more or less holey shadow (size of the holes).

By another hand, please be aware of the fact that this shader seems to properly receive shadows from "Point" and "Spot" lights only (no interesting result from "Directional" ones).
