[gef-dev] Poll about connection anchor usage

[Randy Hudson <hudsonr@xxxxxxxxxx>]

How many of you are calling the method
Figure#fireFigureMoved() directly from your code?  Or in general if
you are notifiying FigureListener#figureMoved(...)

This notification is currently relied
upon by AbstractConnectionAnchor so that it can notify when it's absolute
location has changed, which requires that any attached connections be re-routed.
 The problem is that "figure moved" occurs too often and
in situations where the connection's don't really need to be re-routed.
 One example is when the editor is resized.  The root figure's
width changes, which notifies every anchor and reroutes every connection.
 This can be a performance problem.

My proposed solution is to create a
new type of notification for  "coordinate system" changes.
 Most figures are not coordinate systems, and would not need to fire
this notification.  But anyone currently notifiying figure moved would
be broken because anchors would no longer be depending on this type of
notification.

The response to this poll will determine
the way in which we provide backwards compatibility.  thanks!
