Determine if two coplanar line segments, a and b, intersect.

Line segment a has end points a0 and a1, and line segment b has endpoints b0 and b1. Algorithm from http://stackoverflow.com/questions/563198/how-do-you-detect-where-two-line-segments-intersect

◆ rotate2D()

static std::pair<Double, Double> casacore::Geometry::rotate2D	(	Double	x,
		Double	y,
		const Quantity &	theta
	)
