TurbulencePrimitive	A primitive that fills its subregion with Perlin noise: `feTurbulence` of SVG.
VectorPath	An immutable sequence of contours made of straight segments, Bézier curves and arcs of ellipses, built with a `VectorPathBuilder` and drawn with `DrawingCanvas.Fill` or `DrawingCanvas.Stroke`.
VectorPathBuilder	Builds a `VectorPath`.
VectorPathMeasure	The chords of a path, computed once, to answer many questions about its length, its points and its directions: the position of a marker that moves along the path, or the point a pointer snaps to as it moves.

Structs

Name	Description
CornerRadii	The radius of each corner of a rounded rectangle. A corner whose radius is zero is not rounded.
DrawingCanvas	The drawing surface handed to the callback of `ImageFrame.Draw` or `Image.Draw`. It is only valid until the callback returns.

GradientStop	A color at a position of a gradient.
PathSegment	An element of a `VectorPath`, as `VectorPath.EnumerateSegments` gives it: the start of a contour, a straight segment, a Bézier curve, an arc of an ellipse, or the end of a closed contour.
PathSegmentEnumerator	Enumerates the segments of a `VectorPath`, without allocating. See `VectorPath.EnumerateSegments`.
