RoundingRadius

RoundingRadius
is an option for Rectangle, Framed, and related functions that specifies the radius of the circle to use in rendering rounded corners.

RoundingRadius->r specifies that corners should be drawn using a quarter-circle of radius r.

	r	distance r in ordinary graphics coordinates
	Scaled[s], ImageScaled[s]	fraction s of the size of the graphic
	Offset[d]	d printer's points

For constructs such as Framed, RoundingRadius->r always specifies the radius in absolute printer's points.

The effective radius used for any corner is limited to the half-length of each adjacent side.
