The winding rule for the path (same as in SVGs). This determines whether a given point in space is inside or outside the path.
windingRule: "NONZERO" | "EVENODD" | "NONE" [readonly]
Winding rules work off a concept called the winding number, which tells you for a given point how many times the path winds around that point. This is described in much more detail here. This field can have three possible values:
"NONZERO": The point is considered inside the path if the winding number is NONZERO.
"EVENODD": The point is considered inside the path if the winding number is odd.
"NONE": An open path won’t have a fill.
