The UID of this drawable object.
Add a vertex to the end of the vertices array.
The vertex to add.
Calculate the area of the given polygon (unsigned).
Note that this does not work for self-intersecting polygons.
Check if the given vertex is inside this polygon.

The vertex to check. The new x-component.
True if the passed vertex is inside this polygon. The polygon is considered closed.
Get the bounding box (bounds) of this polygon.
The rectangular bounds of this polygon.
Get the polygon vertex at the given position (index).
The index may exceed the total vertex count, and will be wrapped around then (modulo).
For k >= 0:
The index of the desired vertex.
At the given index.
Get the winding order of this polgon: clockwise or counterclockwise.
Calulate the signed polyon area by interpreting the polygon as a matrix and calculating its determinant.
Convert this polygon to a sequence of cubic Bézier curves.
The first vertex in the returned array is the start point.
The following sequence are triplets of (first-control-point, secnond-control-point, end-point):
startPoint, controlPoint0_0, controlPoint1_1, pathPoint1, controlPoint1_0, controlPoint1_1, ..., endPoint
An optional threshold (default=1.0) how strong the curve segments should over-/under-drive. Should be between 0.0 and 1.0 for best results but other values are allowed.
An array of 2d vertices that shape the cubic Bézier curve.
Convert this polygon to a cubic bezier path instance.
The threshold, usually from 0.0 to 1.0.
Convert this polygon to a cubic bezier curve, represented as an SVG data string.
The 'd' part for an SVG 'path' element.
Convert this polygon to a sequence of quadratic Bézier curves.
The first vertex in the returned array is the start point.
The following sequence are pairs of control-point-and-end-point:
startPoint, controlPoint0, pathPoint1, controlPoint1, pathPoint2, controlPoint2, ..., endPoint
An array of 2d vertices that shape the quadratic Bézier curve.
Convert this polygon to a quadratic bezier curve, represented as an SVG data string.
The 'd' part for an SVG 'path' element.
Create an SVG representation of this polygon.
An optional set of options, like 'className'.
The SVG string.
