The general idea lgtm.

does vangelis already use surfaces for this?

lgtm, though in the future we may want a more general extension set of
parameters.

Overall lgtm. But I am wondering why we have a DF Text Context at all when DF is
disabled (not new with this CL).

Because we can enable DF Text on a per-SkPaint basis. If we agree that we can
get rid of that flag, then we can create the DFTextContext only when we need it.

Oh, right! Maybe we can kill the paint flag once this lands and Chromium has a
flag.
