49 * The output of this effect is a modulation of the input color and coverage for a circle. It
50 * operates in a space normalized by the circle radius (outer radius in the case of a stroke)
51 * with origin at the circle center. Three vertex attributes are used:
63 * Round caps for stroking are allowed as well. The caps are specified as two circle center points
