  Media does not act like an object. It cannot reflect nor refract rays,
nor it has a surface other than defined by a true object. You cannot
have a media "object" all by itself; either it is contained by a true
object or it occupies the entire universe.

  POV-Ray only handles surfaces, not solid objects. It's basically
impossible to handle solid objects with raytracing.

  What's the difference, you might ask? The difference is that when you
apply a texture to an object, the texture is applied to the surface only
(because the object is a surface, nothing more). This is evident when
parts of the texture are transparent.
  It's also evident when you clip an object.
