When points are close together in 2D view space the eraser intersection function does not have a valid direction vector (zero). This cancels out terms in the computation that would still contribute to the result and the function always returns zero intersections. This patch adds a special case when the direction vector is zero, so the point distance to the circle is still calculated (just not in any particular direction).
