TransformOvalToPolygon()

		const VECTOR2I &	aStart,
		const VECTOR2I &	aEnd,
		int	aWidth,
		int	aError,
		ERROR_LOC	aErrorLoc,
		int	aMinSegCount = 0
	)

Convert a oblong shape to a polygon, using multiple segments.

It is similar to TransformRoundedEndsSegmentToPolygon, but the polygon is outside the actual oblong shape (a segment with rounded ends). It is suitable to create oblong clearance areas because multiple segments create a smaller area than the circle. The radius of the circle to approximate must be bigger ( radius*aCorrectionFactor) to create segments outside the circle.

Parameters

aBuffer	is a buffer to store the polygon.
aStart	is the first point of the segment.
aEnd	is the second point of the segment.
aWidth	is the width of the segment.
aError	is the internal units allowed for error in approximation.
aErrorLoc	determines if the approximation error be placed outside or inside the polygon.
aMinSegCount	is the min count of segments to approximate. Default = 0 to do not force a min count.
