+// Section: Debugging polygons
+
+// Module: debug_polygon()
+// Usage:
+//   debug_polygon(points, paths, [convexity=], [size=]);
+// Description:
+//   A drop-in replacement for `polygon()` that renders and labels the path points.
+// Arguments:
+//   points = The array of 2D polygon vertices.
+//   paths = The path connections between the vertices.
+//   ---
+//   convexity = The max number of walls a ray can pass through the given polygon paths.
+//   size = The base size of the line and labels.
+// Example(Big2D):
+//   debug_polygon(
+//       points=concat(
+//           regular_ngon(or=10, n=8),
+//           regular_ngon(or=8, n=8)
+//       ),
+//       paths=[
+//           [for (i=[0:7]) i],
+//           [for (i=[15:-1:8]) i]
+//       ]
+//   );
