Autoscale map on analysis pane when moving the divider

[cugarteblair]

The map has a resize handle.
It would be perferable to have it autoscale

This is a "nice to have" but not essential if it requieres a lot of effort. As long as people know there is a resize handle in lower right corner, they can do the "two-step" adjustment to resize the panes, then resize the map.
