	Yes but how is CURTAIN defined? From what you said, I
believe it was done in spatch and therefore it is made of
bezier patches which can't be differenced... Try this
instead:
object {
  CURTAIN rotate<90,180,180> scale 1 translate <1,2,0>
  clipped_by {
    union {
      cylinder ...
    }
  }
}

PS: After reading your original post again, it seems I
didn't get your problem... Were you saying you couldn't cut
the holes in the curtain (wich is the object of the section
of manual you quote) or you couldn't texture it to your
satisfaction because of the way image_maps work?
