Detailed Description

Implementation of PlanarFigure representing a Bezier curve.

A Bezier curve defined by an arbitrary number of control points (minimum 2). The curve is evaluated using the De Casteljau algorithm. The number of line segments used to approximate the smooth curve is configurable via SetNumberOfSegments().

The control polygon (lines connecting control points) is drawn as a helper polyline for visual reference.

Provides one feature: the curve length (FEATURE_ID_LENGTH).
