Fix winding order check for negative scale in tesselated path rendering.  The isCCW() code in GrTesselatedPathRenderer was using untransformed vertices, which fails for transforms with negative scale.  Doing the check after transformation fixes it.  This was causing some missing geometry in the PolyToPoly and Shapes tests in SampleApp.
