Annotations
A gridded surface is a parametric curve
   surface derived from a rectangular grid in the parameter
   space. The rows from this grid are control points for
   horizontal surface curves; the columns are control points
   for vertical surface curves. The working assumption is that
   for a pair of parametric co-ordinates (s, t) that the
   horizontal curves for each integer offset are calculated
   and evaluated at "s". The defines a sequence of control
   points:
   
   cn(s) : s  1 .....columns 

   From this sequence a vertical curve is calculated for "s",
   and evaluated at "t". In most cases, the order of
   calculation (horizontal-vertical vs. vertical-horizontal)
   does not make a difference. Where it does, the horizontal-   
   vertical order shall be the one used.

   Logically, any pair of curve interpolation types can lead
   to a subtype of GriddedSurface. The following clauses
   define some most commonly encountered surfaces that can
   be represented in this manner.
