Class CM3LayerTerrain extends CM3Layer

CM3LayerTerrain Class

Manages a layer that contains an image of the terrain
This can include:
- A DEM for elevation values
- An image to overlay on the DEM
- A bump map to add surface texture
- A reflectance map to change how light interacts with the surface
