//AutoWidthThreshold: When JoinStyle = jsAuto, this is the threshold at which lines joins will be rounded instead of squared.
With wider strokes, rounded joins generally look better, but as rounding is more complex it also requries more processing and hence is slower to execute.

AutoWidthThreshold: double = 5.0;

//Line widths of less than about 1.3 will produce noticeable Moire pattern when the lines are nearly horizontal or nearly vertical.

MinStrokeWidth: double = 1.33;

//DefaultMiterLimit avoids excessive spikes when line offsetting.
