+    whether or not the box is "active" (a module exists there). If
+    ``needs_neighbors`` is set to True, then the method should also accept a
+    ``neighbors`` kwarg (the neighboring pixels).
+
+    It is frequently necessary to also implement an "initialize" function to
+    set up values that only the containing Image class knows about.
+
+    For examples of what these look like, see doc/module_drawers.png
