[Werner LEMBERG]

> 1d. Enhance core variation capability with "avar2" (support for
>     user-facing vs internal axis distinction and the mapping between
>     them); explicitly support HOI as Underware have demo'd it; and
>     make more efficient storage of sparse variation data.

Note that FreeType 2.13 supports 'avar' version 2, using a patch from
Behdad.
