Make sure we do not treat as circles entities that we really should
treat as squares (such as trees). This fixes an issue reported by Stan.
Make sure we never forget about our destination if we are blocked by
unit obstructions. This makes sure that units in a group but not in
formation will not be blocked by the other units, and probably makes the
general behavior more sane. Helps following [17166]
Refs #3505, #3471, #3376
This was SVN commit r17191.
Change the way the long-range pathfinder rasterisation works slightly so
that we have a better compatibility with the short-range pathfinder.
Should fix the "stuck units" issues, though I am not sure so I am not
marking them as fixed so far. Refs #3471, #3505, and possibly #3292.
Caveat: I am now using clearance of 0.8 for "default" class, which might
have side-effects: please report anything weird.
Also fix leftover style issues.
This was SVN commit r17161.
