+2014-09-27 Overhauled `colors.LightSource`.  Added `LightSource.hillshade` to
+	   allow the independent generation of illumination maps. Added new
+	   types of blending for creating more visually appealing shaded relief
+	   plots (e.g.  `blend_mode="overlay"`, etc, in addition to the legacy
+	   "hsv" mode).
