No, this shouldn't be here.  Your example images clearly show that the effective
baseline didn't actually move.

-baselineAdjust isn't used to adjust the baseline. It's used to control the size
of the drawing rect. I can rename it if you like.

That seems like a good idea, then.

   return kBaselineAdjust;
