Operations
A model of this concept must provide:
Kernel::Point_2	operator() (const Kernel::Plane_3 &h, const Kernel::Point_3 &p)
	returns the image point of the projection of p under an affine transformation, which maps h onto the \( xy\)-plane, with the \( z\)-coordinate removed.

Kernel::Point_2 Kernel::ConstructProjectedXYPoint_2::operator()	(	const Kernel::Plane_3 &	h,
		const Kernel::Point_3 &	p
	)

returns the image point of the projection of p under an affine transformation, which maps h onto the \( xy\)-plane, with the \( z\)-coordinate removed.

This affine transformation must be the inverse of the affine transformation used in ConstructLiftedPoint_3.
