		bool	stippled = false
	)			[static]

Draws a part of a ellipse.

Parameters:

	c	center of the ellipse
	r1	one of the two half axes of the ellipse
	r2	one of the two half axes of the ellipse
	b1	relative limit (between [-1,1]) on short axis to define one end of the part which has to be drawn
	b2	see b1
	n	defines in how much segments the ellipse should be devides
	stippled	defines whether the part has to be drawn normally (false) or stippled (true)

static void View2DDraw::drawRing	(	ml::vec2	c,
		double	r1,
		double	r2,
		int	n = 50
	)			[static]

draws ring or disk subdivided into n segments, using TRIANGLE_STRIP c, r1, and r2 are given in device coordinates, r1 may be zero
