### alphashape/DemoAlphaShape
### alphashape/DemoAlphaShape01
Demonstrates the use of [AlphaShape] to create a [org.openrndr.shape.ShapeContour] out
of a collection of random [Vector2] points. Unlike the convex hull, an Alpha shape can be concave.

### alphashape/DemoAlphaShape02
Demonstrates the use of [AlphaShape] to create ten
[org.openrndr.shape.ShapeContour] instances out of a collection of random [Vector2] points.
The same points are used for each contour, but an increased alpha parameter
is passed to the AlphaShape algorithm. Higher values return more convex shapes
= shapes with a larger surface.
The list of shapes is reversed to draw the smaller contours on top, otherwise only
the last one would be visible.
An instance of [Random] with a fixed seed is used to ensure the resulting
random shape is always the same.
