24/// **Component**: A line strip in 2D space.
25///
26/// A line strip is a list of points connected by line segments. It can be used to draw
27/// approximations of smooth curves.
28///
29/// The points will be connected in order, like so:
30/// ```text
31///        2------3     5
32///       /        \   /
33/// 0----1          \ /
