 The scale settings don't matter - it is that scale dependent rendering is
 enabled and that the overview map has no scale (some default, actually).

 The overview may show the layer if it was displayed before the scale
 dependent rendering was enabled, but will disappear when the overview is
 redrawn as on a layer visibility change.

 The patch provided adds a test for mOverview in QgsMapRenderer::render()
 so the layer will be rendered if it has been added to the overview map.
