Werner Lemberg 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>.

Werner Lemberg c8c7ad7910 [autofit] Add support for Georgian scripts.
Georgian is problematic, since `uppercase' forms of Mkhedruli
(called Mtavruli) are not yet defined in Unicode, which means that
proper blue zones can't be defined.  However, there is already a
proposal submitted to Unicode; see

  http://www.unicode.org/L2/L2016/16034-n4707-georgian.pdf

Additionally, due to historical reasons, Unicode treats Khutsuri as
the same script as Mkhedruli, and so does OpenType.  However, since
the two scripts have completely different shapes it can happen that
blue zones differ considerably.  The tag `geok' used here (derived
from ISO 15924) to differentiate the two scripts is not an OpenType
tag in use.  If we now have a font that contains both glyphs for
Mkhedruli and Khutsuri, and it uses OpenType features for both also,
HarfBuzz unavoidably treats all glyphs as `geor'.  As a consequence,
blue zones for `geok' are not used for glyphs involved in the
OpenType features.

An issue not yet resolved is which OpenType feature should be used
to access Mtavruli glyph shapes; right now, FreeType doesn't set up
support for them, but it is easy to add them later on as soon as
more information is available.
