Spawn generation generally tries to place spawns:
- In spacious areas
- Away from the center (true center or mirror lines)
- Away from a symmetry-projected spawn
- Away from previously placed spawns
This commit introduces the following adjustments:
- The spacing between sequentially placed spawns is relaxed.
- Fix spawn mines contributing too much to the space reservation.
- Factor rotations into anti-center biasing calculation.
- Preserve spacing information in center space fallback decisions.
- Use a linear (instead of binary) falloff for anti-center biasing.
- Enforce that spawns have a minimum buildable area around them.
- Enforce that symmetry-projected spawns have as much separation as
sequentially placed spawns would.
- Allow spawns on or near roads.
