inverse()

auto projection::albers_equal_area::ellipsoid::inverse	(	const auto	x,
		const auto	y )

Inverts the Albers Equal-Area Conic projection for WGS_1984 and returns the geographic coordinates (longitude, latitude in degrees) corresponding to the given planar coordinates (x, y in meters).

The function uses an iterative Newton-like method to recover the latitude from the projected y-coordinate, based on the equations in USGS Professional Paper 1395.
