* \brief Tile the terrain
*
* This function recursively walks the scene graph and sorts all
* triangles into a grid of smaller graphs. This reduces the
* calculation effort: If the position of the plane and therefore
* the grid below it is known, only a small fraction of all
* triangles has to be tested.
*
* During the recursive walk down the tree, the function tracks
* all transformations. If a leaf node is encountered, the contained
* triangles are transformed by the tracked transformations to
* get the absolute position of each triangle. Then all triangles
* are sorted into the grid by their absolute position.
