1dee4bf9f7 [autofit] Use better blue zone characters for lowercase latin.
The number of lowercase characters for computing the top flat blue
zone value was too small (in most cases only `x' and `z').  If one
of the two characters has a large serif, say, it can happen that
FreeType must select between two different values, having a 50%
chance to use the wrong one.  As a result, rendering at larger PPEM
values could yield uneven lowercase glyph heights.

Problem reported by Christoph Koeberlin <christoph@koe.berlin>.

* src/autofit/afblue.dat (AF_BLUE_STRING_LATIN_SMALL): Replaced
with...
(AF_BLUE_STRING_LATIN_SMALL_TOP, AF_BLUE_STRING_LATIN_SMALL_BOTTOM):
... New, extended sets.
(AF_BLUE_STRINGSET_LATN): Updated.

fa437d8d3c [cff] Provide metrics variation service interface (#50196).
Only now I've got an OTF with an HVAR table for testing...

The code in `ftmm.c' uses `FT_FACE_LOOKUP_SERVICE' to get the
metrics variations interface.  However, this didn't work with
`FT_FACE_FIND_GLOBAL_SERVICE' used in `sfnt_init_face'.

* src/cff/cffdrivr.c: Include FT_SERVICE_METRICS_VARIATIONS_H.
(cff_hadvance_adjust, cff_metrics_adjust): Wrapper functions for
metric service functions from the `truetype' module.
(cff_service_metrics_variations): New service.
(cff_services): Updated.

* src/cff/cffpic.h (CFF_SERVICE_METRICS_VAR_GET): New macro.
[FT_CONFIG_OPTION_PIC]: Synchronize code.

* src/sfnt/sfobjs.c (sfnt_init_face): Replace call to
FT_FACE_FIND_GLOBAL_SERVICE with `ft_module_get_service' to always
load the service from the `truetype' module.
