This implementation is fatally flawed in a couple ways, the most
important of which is related to multiple windows on separate monitors.
Basically the refresh would cause recreation of action zones when they
are not expected to change, resulting in complaint #141521. This also
causes too many refreshes of gizmos. I don't currently have any ideas
on a better way of doing this so we'll have to do without for now.
