PathOps tests internal routines direcctly. Check to make sure that test points, lines, quads, curves, triangles, and bounds read from arrays are valid (i.e., don't contain NaN) before calling the test function. Repurpose the test flags. - make 'v' verbose test region output against path output - make 'z' single threaded (before it made it multithreaded) The latter change speeds up tests run by the buildbot by 2x to 3x.
