GrTessellator: make inverse fill types more sane.
In the screenspace AA tessellator, a path's fill types would be applied
twice: once when extracting contours, and then again when filling polys.
It was supposed to be forced to kWinding_FillType by the second call to
mesh_to_polys(), but for hysterical reasons this parameter is unused!
For kInverseWinding_FillType (the only mode where this actually caused a bug),
I unwittingly papered over the problem by reversing the outer contour for the
inverse fill types, and comparing against -1 instead of 1.
The better fix is to actually pass a winding mode of kWinding_FillType
to polys_to_triangles(), and remove the (ignored) param from mesh_to_polys().
Then we can pass a clockwise outer contour as before, and compare
against 1 instead of -1.
