+/*! /class PolySet
+
+	The PolySet class fulfils multiple tasks, partially for historical reasons.
+	FIXME: It's a bit messy and is a prime target for refactoring.
+
+	1) Store 2D and 3D polygon meshes from all origins
+	2) Store 2D outlines, used for rendering edges
+	3) Rendering of polygons and edges
