### hobbycurve/DemoHobbyCurve04
Demonstrates the use of the `tensions` argument when creating a Hobby curve.
The program starts by creating a random set of scattered points with enough separation between them.
The points are sorted using `hilbertOrder` to minimize the travel distance when visiting all the points.
Finally, we draw a set of 40 hobby translucent curves using those same points but with varying tensions.

### hobbycurve/DemoHobbyCurve05
Demonstrates the creation of a 40 hobby curves with 10 points each.
The control points in all hobby curves are almost identical, varying only
due to a slight increase in one of the arguments of a simplex noise call.
The program shows that minor displacements in control points can have
a large impact in the resulting curve.

### primitives/DemoRectangleIrregularGrid02
Demonstrates how to use `Rectangle.irregularGrid()` to create a grid with varying column widths
and row heights. The widths and heights are specified as a list of 13 `Double` values, each
picked randomly between the values 1.0 and 4.0. This produces two types of columns and two
types of rows only: wide ones and narrow ones.
The program also demonstrates how to query a `row()` and a `column()` from a `RectangleGrid` instance,
both of which return a `List<Rectangle>`. Both `Rectangle` lists are rendered with translucent
colors, which makes the intersection of the column and the row slightly brighter.

### primitives/DemoTear02
Demonstrates the use of `Tear()` to create drop-like shapes out of a Vector2 point and a Circle.
The tear locations are calculated using the `Rectangle.scatter()` function. Locations near the
center of the window are filtered out.
The radii of each tear is randomly chosen between three values. The orientation of each tear
is calculated by getting the normalized difference between the tear and the center of the window,
making them look as being emitted at the center of the window.
