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