+Three equations combine to describe the boundaries of the arc
+
+x^2/w^2 + y^2/h^2 = 1 ellipse itself
+(X-x)^2 + (Y-y)^2 = r^2 circle at (x, y) on the ellipse
+(Y-y) = (X-x)*w^2*y/(h^2*x) normal at (x, y) on the ellipse
+
+These lead to a quartic relating Y and y
+
+y^4 - (2Y)y^3 + (Y^2 + (h^4 - w^2*r^2)/(w^2 - h^2))y^2
+ - (2Y*h^4/(w^2 - h^2))y + (Y^2*h^4)/(w^2 - h^2) = 0
+
+The reducible cubic obtained from this quartic is
+
+z^3 - (3N)z^2 - 2V = 0
+
+where
+
+N = (Y^2 + (h^4 - w^2*r^2/(w^2 - h^2)))/6
+V = w^2*r^2*Y^2*h^4/(4 *(w^2 - h^2)^2)
+
+Let
+
+t = z - N
+p = -N^2
+q = -N^3 - V
+
+Then we get
+
+t^3 + 3pt + 2q = 0
+
+The discriminant of this cubic is
+
+D = q^2 + p^3
+
+When D > 0, a real root is obtained as
+
+z = N + cbrt(-q+sqrt(D)) + cbrt(-q-sqrt(D))
+
+When D < 0, a real root is obtained as
+
+z = N - 2m*cos(acos(-q/m^3)/3)
+
+where
+
+m = sqrt(|p|) * sign(q)
+
+Given a real root Z of the cubic, the roots of the quartic are the roots
+of the two quadratics
+
+y^2 + ((b+A)/2)y + (Z + (bZ - d)/A) = 0
+
+where
+
+A = +/- sqrt(8Z + b^2 - 4c)
+b, c, d are the cubic, quadratic, and linear coefficients of the quartic
+
+Some experimentation is then required to determine which solutions
+correspond to the inner and outer boundaries.
