Without blue zone treatment, glyphs always have uneven bottom line. I
think the warp can be combined with bluezone management.

If the bottom line of the warped glyph is shifted away from a bluezone,
then the whole glyph should be shifted back a whole 1 pixel back toward
the bluezone after being warped.
