Reason for revert:
broke unittests

Original issue's description:
> fix the error that path is inversed for stroke and strokeAndFill styles.
>
> However, because hairline stroke + fill = fill (see src/core/SkStrokeRec.cpp), strokeAndFill will be thought as fill style when paint.getStrokeWidth() <= 0, this edge case can be inverse-filled.
