+// The Ecorder cursor only highlights over one of the four Victoria lilies, even
+//  though they all respond to Ecorder clicks. Each lily has a doit method that
+//  highlights the cursor but three of them never execute because they are
+//  added to the room pic. This removes them from the cast and prevents doit.
+//
+// We fix this by removing the addToPic calls so the lilies remain in the cast.
