+	rev K_HEIGHT_MAP_VERSION_4
+
+	This is a major rev of the heightmap chunk. Here's the basic overview of what has happened:
+	We now support multiple boundary areas. They are stored in a vector of ICoord2Ds. The lower-
+	left corner is always (0,0), and the ICoord2D specifies the top-right coordinate.
+	The boundary also contains a name.
