[Freeciv-Dev] (PR#12186) fog error near map boundaries

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

The fog near the boundaries is drawn as if the unreal tiles are known. 
Obviously in this screenshot we want to draw them as if they were 
fogged.  But if the real tiles are known then we want to draw things as 
if they were also known.

I see two possible rules here:

1.  If any of the real tiles at the corner are fogged, the unknown tiles 
should be drawn fogged.

2.  If all of the real tiles at the corner are fogged, the unknown tiles 
should be drawn fogged.
