/**
* Loads Terrain grid tiles with image heightmaps.
* By default it expects a 16-bit grayscale image as the heightmap, but
* you can also call setImageType(BufferedImage.TYPE_) to set it to be a different
* image type. If you do this, you must also set a custom ImageHeightmap that will
* understand and be able to parse the image. By default if you pass in an image of type
* BufferedImage.TYPE_3BYTE_BGR, it will use the ImageBasedHeightMap for you.
