Overview

This program visualizes the quadratic approximation to the circle, used to implement round joins when stroking paths. The approximation is used in the stroking code for arcs between 0 and 45 degrees, but is visualized here between 0 and 90 degrees. The discrepancy between the approximation and the true circle is clearly visible at angles above 65 degrees.
