//! ## Example
//!
//! draw a red star
//! ```
//! use rsille::{color::Color, extra::Turtle, Canvas};
//! let mut c = Canvas::new();
//! let mut t = Turtle::new();
//! t.color(Color::Red);
//! for _ in 0..5 {
//!    t.forward(30.0);
//!    t.right(144.0);
//! }
//! c.paint(&t, 0.0, 15.0).unwrap();
//! c.print();
//! ```
