Straight lines, arcs, ellipses, elliptic curves, and Bezier curves are considered "mark vectors".
A value of NaN, 0 or less than 0 leads to always considering the heading change as being exceeded while a value above π is interpreted as the angle never being exceeded. Therefore in effect, 0 means that skywriting extension are always inserted (unless MergedExtensionsMaxCoH applies). Likewise for values above π, skywriting would only be used at both ends of mark sequences (if the ForceAtStartFinish-mode is set) or at the ends of marks of skywriting sections (if the ForceAtStartAndFinish-mode is set).
