Deprecated.

Determines if a line segment intersects the ellipse and if so finds the point(s) of intersection.

Parameters:

seg - Line segment to test for intersection

pt0 - OUT - intersection point (if it exists)

pt1 - OUT - second intersection point (if it exists)

Returns:

Returns the number of intersection points (0, 1, or 2).
