Computes the bounding box for a curve in 2d . Functions to add a 2D curve to a bounding box. The 2D curve is defined from a Geom2d curve.
Adds to the bounding box B the curve C B is then enlarged by the tolerance value Tol. Note: depending on the type of curve, one of the following representations of the curve C is used to include it in the bounding box B:
 an exact representation if C is built from a line, a circle or a conic curve,
 the poles of the curve if C is built from a Bezier curve or a BSpline curve,
 if not, the points of an approximation of the curve C. Warning C is an adapted curve, that is, an object which is an interface between:
 the services provided by a 2D curve from the package Geom2d
 and those required of the curve by the computation algorithm. The adapted curve is created in the following way: Handle(Geom2d_Curve) mycurve = ... ; Geom2dAdaptor_Curve C(mycurve); The bounding box B is then enlarged by adding it: Bnd_Box2d B; // ... Standard_Real Tol = ... ; Add2dCurve::Add ( C, Tol, B ); Exceptions Standard_Failure if the curve is built from:
 a Geom_Line, or
 a Geom_Parabola, or
 a Geom_Hyperbola, and P1 and P2 are either two negative infinite real numbers, or two positive infinite real numbers.
