.SH NAME
CTLPT
CPt = CTLPT( ConstantType PtType, NumericType Coord1, ... )
Constructs a single control point to be used in the construction of curves
and surfaces. Points can have from one to five dimensions, and may be
either Euclidean or Projective (rational). Points' type is set via the
constants E1 to E5 and P1 to P5. The coordinates of the point are specified
in order, weight is first if rational.
Examples:
CPt1 = CTLPT( E3, 0.0, 0.0, 0.0 );
CPt2 = CTLPT( P2, 0.707, 0.707, 0.707 );
constructs an E3 point at the origin and a P2 rational point with
a weight of 0.707. The Projective Pi points are specified as
CTLPT(Pn, W, W X1, ... , W Xn).
