Initial macroquad version for compiletime reasons

```rust
// Movement
plan.forward(100);
plan.backward(50);

// Rotation
plan.left(90);    // degrees
plan.right(45);

// Circular arcs
plan.circle_left(50.0, 180.0, 36);   // radius, angle (degrees), segments
plan.circle_right(50.0, 180.0, 36);  // draws arc to the right

// Pen control
plan.pen_up();
plan.pen_down();

// Appearance
plan.set_color(RED);
plan.set_pen_width(5.0);
plan.hide();
plan.show();

// Turtle shape
plan.shape(ShapeType::Triangle);
plan.shape(ShapeType::Turtle);    // Default classic turtle shape
plan.shape(ShapeType::Circle);
plan.shape(ShapeType::Square);
plan.shape(ShapeType::Arrow);

// Custom shape
let custom = TurtleShape::new(
    vec![vec2(10.0, 0.0), vec2(-5.0, 5.0), vec2(-5.0, -5.0)],
    true  // filled
);
plan.set_shape(custom);

// Chaining
plan.forward(100).right(90).forward(50);
```
