  38. * This is the zero mesher.
  39. * Whatever you want him to mesh, he can't, telling you that by responding with a null pointer.
  40. * Effectivly this is for switching off meshing and for testing as each physics machine should deal
  41. * with the null pointer situation.
  42. * But it's also a convenience thing, as physics machines can rely on having a mesher in any situation, even
  43. * if it's a dump one like this.
  44. * Note, that this mesher is *not* living in a module but in the manager itself, so
  45. * it's always availabe and thus the default in case of configuration errors
