Shouldn't applyToPath just return a path with the correct fill type?

We shouldn't need to look at stroke after calling applyToPath since applyToPath
should return a path that just needs to be filled.

applyToPath doesn't change the style. For a stroke path, it will record the
inner contour and outer contour for filling the area between these two contours.
So it will inverse-stroke for stroke style and strokeAndFill style if we don't
exclude these styles here.

It *should* set the correct fill type.

                 pathPtr = tmpPath.get();
                 stroke.writable()->setFillStyle();
