Description

Method: PolyBezierArcPoints

Params:   X, Y, Width, Height, Angle1, Angle2, Rotation, Points, Count
  Returns:  Nothing

  Use PolyBezierArcPoints to convert an Arc and ArcLength into a Pointer Array
  of TPoints for use with Polyline or Polygon. The Rotation parameter accepts
  a Rotation-Angle for a rotated Ellipse'- for a non-rotated ellipse this
  value would be 0, or 360. The result is an Aproximation based on 1 or more
  Beziers. If the AngleLength is greater than 45 degrees, it recursively breaks
  the Arc into Arcs of 45 degrees or less, and converts them into Beziers with
  BezierArcPoints. The angles are 1/16th of a degree. For example, a full circle
  equals 5760 (16*360). Positive values of Angle and AngleLength mean
  counter-clockwise while negative values mean clockwise direction. Zero
  degrees is at the 3'o clock position. Points is automatically initialized,
  so any existing information is lost, and the array starts at 0. Points
  should ALWAYS be Freed when done by calling to ReallocMem(Points, 0).
