[FEATURE][layouts] Allow control over stacking position of map overvi…
Browse files Browse the repository at this point in the history 
…ew extents

Allows overview extents to be drawn below map labels (the new default),
but also adds choices for drawing them below all map layers, or
above/below a specific map layer.

This allows users to control exactly where in the map item's layer stack
the overview will be placed, e.g. allowing them to draw a overview
extent below some feature layers such as roads whilst drawing it
above other background layers.
