Class Name

---

  MGHgrLegoSurface

Purpose

---

  A surface class that acts sanely when the STYLE property is set to
  one of the Lego values (5 or 6).

Properties

---

  This class supports all the properties of MGHgrSurface, with a few
  differences in the behaviour of the DATAX, DATAY, DATAZ and STYLE
  properties.
    - For lego surfaces (STYLE equals 5 or 6), DATAZ is dimensioned
      according to the number of visible cells, not the the number
      of vertices. DATAX and DATAY still specify vertex positions
      and are dimensioned according to the number of vertices. Thus
      for a lego surface with m x n vertices, DATAX is
      dimensioned [m] or [m,n], DATAY is dimensioned [n] or [m,n]
      and DATAZ is dimensioned [m-1,n-1].
