 In Fusion 2.0, we introduced a feature that visually activated all
 instances of the same widget so that when a toolbar widget was activated,
 the same type of widget on the context menu would be activated and vice-
 versa.  This works well for simple widgets such as Pan but falls short if
 instances of the same widget have different behaviour based on their
 configuration.  The most obvious example of this is the Zoom widget, which
 can be configured to zoom in or out.

 The proposed fix is to add a new method to Widget.js called
 shouldActivateWith that takes a widget as an argument.  The default
 behaviour will be to return true but specific widgets can overload this
 method and return false if the widget is not configured the same way.

 This may apply to other widgets such as Select which can be configured to
 select on the active layer only or all layers.  Two instances with
 different settings should not be activated together.
