performance
Grid shapes are not nearly performant enough yet to support this case. The special `range == 0` case is now documented, and the `GridlessGrid.getGridArea()` override relies on it now instead of duplicating the case.

Fixes performance issue for #4980
Description of the Change
This restores the special case where a sight with no distance will produce a circular visible area that goes out to the map's Vision Distance setting. Grid shapes are not nearly performant enough yet to support that case, and it's not clear whether it's even desirable behaviour.
The key to the change is to hit the special case of
range == 0forGrid.getGridArea(). This case is now documented, and the override inGridlessGridrelies on it instead of duplicating the case logic.Possible Drawbacks
None, this bring back long-standing behaviour.
