Terrain modifier that defines an area of sloped height.
This modifier creates a sloped area. The center point is set to a level and all other points are set based on specified gradients.

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()
