Close enough anyway.  Simply that it would take at least two objects,
whether it be plane + plane, box (infinitely thin) + box, polygon + box, or
whatever.  One to hold the image, one to act as layer over it.  Except what
you describe means yet another polygon would be needed to place in front of
the image polygon, for the way I was talking about.  Which is a physical
object layer holding a transparent yet normal and finish modified surface on
top of a unmodified image.

Might seem more complicated than it is, but that's how I might proceed to
work around the "cannot layer patterned textures" problem that otherwise
happens with a material map being applied as layered texture.
