/** Example 017 Helloworld mobile for WinCE 6. DEPRECATED
This was Example 017 Helloworld mobile for WinCE 6.
But WinCE6 support has been removed for Irrlicht 1.9.
If you still need that please use Irrlicht 1.8 or svn revision 5045 which was the last one to include it.
Sources still kept for now as it compiles on other platform too. And we might use this example again
once we support Windows RT.

Here comes the terrain renderer scene node: We add it just like any

file name to the heightmap we use. A heightmap is simply a gray scale
texture. The terrain renderer loads it and creates the 3D terrain from
it.
To make the terrain look more big, we change the scale factor of
it to (40, 4.4, 40). Because we don't have any dynamic lights in the
scene, we switch off the lighting, and we set the file
terrain-texture.jpg as texture for the terrain and detailmap3.jpg as
second texture, called detail map. At last, we set the scale values for
the texture: The first texture will be repeated only one time over the
whole terrain, and the second one (detail map) 20 times.
