Apply this modifier on a terrain segment.
The segment is at x,y in local coordinates. Output is placed into point.
Implemented in Mercator::CraterTerrainMod< Shape >, Mercator::SlopeTerrainMod< Shape >, Mercator::AdjustTerrainMod< Shape >, and Mercator::LevelTerrainMod< Shape >.

Function used to apply this mod to existing points.
This makes the basic mods much more powerful without the need for extra classes. It completely obsoletes AdjustTerrainMod, which is now the same as LevelTerrainMod with this function changed from set() to sum()
