* The non-documented WITH_VTK is no longer supported.
* The function CGAL::Image_3::read_vtk_image_data
has been replaced by a global function.
* Added Mesh_3/examples/Mesh_3/mesh_3D_gray_vtk_image.cpp
That assertion verifies that the value `value_outside` is considered at
a value *outside* of the domain. Otherwise Mesh_3 will crash with an
assertion saying that "infinite cells should not be in the C3t3".
That is an attempt to fix a warning:
```
