* an object involves going inside C but without entering S.)
* o Draw connectors to shape edges rather than bounding box.
* o Show a visual indicator for objects with the 'avoid' property set.
+ * o Allow user to change a object between a path and connector through
+ * the interface.
* o Create an interface for setting markers (arrow heads).
* o Better distinguish between paths and connectors to prevent problems
* in the node tool and paths accidently being turned into connectors
* in the connector tool. Perhaps have a way to convert between.
* o Only call libavoid's updateEndPoint as required. Currently we do it
* for both endpoints, even if only one is moving.
- * o Cleanup to remove unecessary borrowed DrawContext code.
* o Allow user-placeable connection points.
* o Deal sanely with connectors with both endpoints attached to the
* same connection point, and drawing of connectors attaching
