+  * Extended add_plot_option() API
+  
+    This is a backwards-compatible update. There is NO API break. Two new
+    features:
+
+    - multiple key/value sets can be set in a single call by using keyword
+      arguments
+
+    - "overwrite" kwarg can be used to overwrite previously-set keys OR to
+      leave the previous ones without barfing
