//! Cheese example - demonstrates multi-contour fills with holes
//!
//! This example creates a cheese-like shape by:
//! 1. Drawing the outer square boundary
//! 2. Lifting the pen (pen_up) to close that contour
//! 3. Drawing circular and triangular holes with pen_up/pen_down
//!
//! Lyon's EvenOdd fill rule automatically creates holes where contours overlap!
