Firstly, if you want to substract an object from another, they should not
have councident surfaces. That is, if you want to for example cut a hole
through a box with another box, the cutting box should be slightly
longer in the direction of the hole.

  Secondly, in the resulting object the surfaces which belong to the
cutting object, ie the new surfaces which appear in the original object
due to the cutting, will be textured with the cutting object's texture.
(If you want to keep the texture of the original object in these new
surfaces you have to use cutaway_textures.)
