/**
* Subdivide NURB surfaces - nzc 30-5-'00 -
*
* Subdivision of a NURB curve can be effected by adding a
* control point (insertion of a knot), or by raising the
* degree of the functions used to build the NURB. The
* expression
*
* degree = #knots - #controlpoints + 1 (J Walter piece)
* degree = #knots - #controlpoints (Blender
* implementation)
* ( this is confusing.... what is true? Another concern
* is that the JW piece allows the curve to become
* explicitly 1st order derivative discontinuous, while
* this is not what we want here... )
*
* is an invariant for a single NURB curve. Raising the degree
* of the NURB is done elsewhere; the degree is assumed
* constant during this operation. Degree is a property shared
* by all controlpoints in a curve (even though it is stored
* per control point - this can be misleading).
* Adding a knot is done by searching for the place in the
* knot vector where a certain knot value must be inserted, or
* by picking an appropriate knot value between two existing
* ones. The number of controlpoints that is influenced by the
* insertion depends on the order of the curve. A certain
* minimum number of knots is needed to form high-order
* curves, as can be seen from the equation above. In Blender,
* currently NURBs may be up to 6th order, so we modify at
* most 6 points. One point is added. For an n-degree curve,
* n points are discarded, and n+1 points inserted
* (so effectively, n points are modified). (that holds for
* the JW piece, but it seems not for our NURBs)
* In practice, the knot spacing is copied, but the tail
* (the points following the insertion point) need to be
* offset to keep the knot series ascending. The knot series
* is always a series of monotonically ascending integers in
* Blender. When not enough control points are available to
* fit the order, duplicates of the endpoints are added as
* needed.
