/*
   There are three kind of spaces in content:
   Generator (G), Mathematic (M), and Visible (V) spaces.
   1. G-space, a space in which a generator computes points.
      Curves in this space are called paths.
   2. M-space, a space to which each G-point is mapped.
      For each G-point there may be several M-points.
      The map G -> M x M ... x M is defined by generator-
      dependent decoder.
      Curves in this space are called traces.
   3. V-space, a space visible in windows and to which
      M-points are mapped by a set of user-defined functions.
      Curves in this space are called shifts.
