Werner Lemberg ec776596ce [autofit] Fix handling of default script.
Patch taken from ttfautohint, commit
071ae2c00e0d67f9d19418f4fade1c23d27dc185.

There were two bugs.

  - We now use non-standard script tags like `khms' for special
    purposes.  However, HarfBuzz maps such tags to `DFLT', and
    without this commit the associated lookups were incorrectly
    assigned to the non-standard tags.

  - Let's assume we have a Bengali font, and the font's `DFLT'
    script tag handles the necessary lookups for Bengali, too.
    Without this commit, the `DFLT' lookups were assigned to
    ttfautohint's default script (usually `latn') before the
    standard lookups for Bengali were handled.

    We now have the following order while searching for covered
    glyph indices.

      special features of scripts (e.g. `sups' for Cyrillic)
      Unicode mappings of scripts
      remaining features of scripts (especially important for Indic
        scripts)
      default features of default script

* src/autofit/afshaper.c, src/autofit/afshaper.h
(af_shaper_get_coverage): Add boolean parameter to indicate default
script.
Update all callers.

* src/autofit/afglobal.c (af_face_globals_compute_style_coverage):
Fix search order for coverages.
