Function sort_poly_boxes 

pub fn sort_poly_boxes(boxes: &[BoundingBox]) -> Vec<BoundingBox>

Sort polygon boxes (N-point bounding boxes) in reading order.

The boxes are sorted by their minimum y-coordinate (top edge), from top to bottom. This is a simpler sorting strategy suitable for arbitrary polygon shapes.

This follows standard poly box sorting implementation.

Arguments

• boxes - Slice of bounding boxes to sort

Returns

A vector of sorted bounding boxes
