issues with parabolic or hyperbolic mirrors

[chbergmann]

mirrors made with parabolic or hyperbolic curves are having issues with reflections. I did not see that sort of behavior with flat surfaces or circle/ellipse based surfaces. I guess a picture is a 1000 words, so there we are

The Optics workbench uses the OpenCascade library to calculate the intersection points between a ray and the curves or surfaces. In some cases it does not return intersection points for hyperbolic or parabolic curves.
The problem has to be fixed inside the openCascade library.

@chbergmann which version of OCC have you tested ?
