Data Fields
long	magic

int	end
	indices
fastf_t	radius
	radius < 0.0 -> full circle with start point on circle and "end" at center
int	center_is_left
	flag indicating where center of curvature is. If non-zero, then center is to left of vector from start to end
int	orientation
	0 -> ccw, !0 -> cw
int	center
	index of vertex at center of arc (only used by rt_extrude_prep and rt_extrude_shot)
