radar toggling (against the 2.0.9 branch code).
The first version simply overlays the radar on
the viewport. Note that the screenshot was taken
at the default '2' radar level, and that the top and
bottom of the radar field are clipped. That's
because I've written the patch to respect the
_radarLimit BZDB variable.
The second version places the viewport where
the radar used to be. The target box sucks in
the screenshot, but that can easily be remedied.
I'm not overly fond of either setup.
