Non-Sampling lineout failing for quadratic cells #1751

Daniel Pino Nunez reported to email list and provided data. Non-Sampling lineout does not work with his data. I believe our intersection code is not handling quadratic cells. Sampling works as a work-around.

Comments: If I triangulate the mesh using the Delaunay operator, then non-sampling lineout works.
