Hello! Turtle is a great project in so many ways. 💕🐢

I noticed that after completing the Rust logo (cargo run --example rust), the cargo process was using ~100% of a core on my MacBook Pro, while the operating system's WindowServer process was using ~15%. This suggests Turtle is still drawing when idle.

I don't know much about the GUI / graphics stacks, so have no idea if this is difficult to fix. 🙃

(Side note: CPU utilisation is also pretty high while drawing, managing to use all four cores on my laptop. Reducing idle CPU utilisation should help with that too!)
