[sfnt] Fix `FT_Get_Advance' for bitmap strikes.
`FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
advance value from the font table and then scales it by the
`font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
set that value for bitmap fonts and the advance gets scaled to zero.

[truetype] Add bytecode support for GX variation fonts.
This commit implements undocumented (but confirmed) stuff from
Apple's old bytecode engine.
GETVARIATION[], opcode 0x91
This opcode pushes normalized variation coordinates for all axes
onto the stack (in 2.14 format). Coordinate of first axis gets
pushed first.
GETINFO[], selector bit 3
If GX variation support is enabled, bit 10 of the result is set
to 1.
* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
bit 3, checking support for variation glyph hinting.
(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
to implement opcode 0x91.
(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.

[smooth] Sub-banding protocol revision.
Rasterization sub-banding is utilized at large sizes while using
rather small fixed memory pool. Indeed it is possible to make an
educated guess how much memory is necessary at a given size for a
given glyph. It turns out that, for large majority of European glyphs,
you should store about 8 times more boundary pixels than their height.
Or, vice versa, if your memory pool can hold 800 pixels the band
height should be 100 and you should sub-band anything larger than
that. Should you still run out of memory, FreeType bisects the band
but you have wasted some time. This is what has been implemented in
FreeType since the beginning.
It was overlooked, however, that the top band could grow to twice the
default band size leading to unnecessary memory overflows there. This
commit fixes that. Now the bands are distributed more evenly and
cannot exceed the default size.
Now the magic number 8 is really suitable for rather simple European
scripts. For complex Chinese logograms the magic number should be 13
but that is subject for another day.
* src/smooth/ftgrays.c (gray_convert_glyph): Revise sub-banding
protocol.

* src/autofit/afranges.c: Remove `UL' postfix from hex numbers.
Suggested by Alexei. `UL' is only needed for 16bit compilers, but
it seems noone is using this anymore (and we no longer test whether
FreeType compiles in such an environment). Otherwise, it is easy to
add the postfix to the `AF_UNICODE_RANGE' macro.

[smooth] Shrink bisection stack.
The convergence of Bézier flatteners is fast with the deviation
from straight line being assymptotically cut 4-fold on each bisection.
This justifies smaller bisection stack size.

(gray_render_conic): Create and use conic `bez_stack'. Move back the
band analysis from...
(gray_conic_to): ... here.
(gray_render_cubic): Create and use cubic `bez_stack'. Move back the

[truetype] Improve the recursive reference detector.
The previous fix for #46372 misunderstood a composite glyph referring
same component twice as a recursive reference. See the discussion
http://lists.gnu.org/archive/html/freetype/2016-05/msg00000.html
Thanks to Khaled Hosny for finding this issue.

the i-th node from FT_List. (load_truetype_glyph): In the traversal

[smooth] More efficient accounting of conic splits and draws.
A single decrement counter of segments to draw, instead of an array,
contains all the information necessary to decide when to split and
when to draw a conic segment. The number of splits before each draw is
equal to the number of trailing zeros in the counter.
* src/smooth/ftgrays.c (gray_TWorker): Remove `lev_stack'.
(gray_render_conic): Updated to use decrement counter of segments.

[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.
* src/autofit/afblue.dat: Add blue zone data for Georgian.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Georgian standard characters.

Even if the dummy hinter is used as the handler for `none' (which
doesn't use blue zones), it is more consistent than the old value
(which was 0), pointing to Arabic...
