Detailed Description

The output color of this effect is a modulation of the input color and a sample from a distance field texture (using a smoothed step function near 0.5). It allows explicit specification of the filtering and wrap modes (GrSamplerState). The input coords are a custom attribute. No gamma correct blending is applied. Used for paths only.
