This is a noisey commit due to a few const changes.
The actual meat of it is a new TerrainColorEarthLikeHeightmapped.cpp file which splits the heightmap using branches out of TerrainColorEarthLike.cpp and simplifies them both in due course.
Also TerrainColorTFPoor.cpp no longer has the heightmap branches since IT NEVER USED THEM.
Assert and const again.
Assert bounds check and if null checking.
