2D Spline Curve Intersections Dimension Mismatch Exception

[rjc8237]

The CvCvIntersector method is throwing an exception with the message Dimension mismatch for 2D rational spline curves. The method works without issues for 3D curves. While debugging this issue, I noticed that the intersector is computing a cross product.

The exception can be reproduced with test_CvCvIntersector.h in the intersections module and the two attached curves.
