+// Purpose: Implements the cordon tool. The cordon tool defines a rectangular
+//			volume that acts as a visibility filter. Only objects that intersect
+//			the cordon are rendered in the views. When saving the MAP file while
+//			the cordon tool is active, only brushes that intersect the cordon
+//			bounds are saved. The cordon box is replaced by brushes in order to
+//			seal the map.
