Dominik Röttsches ba4bd5b994 Add `TT_CONFIG_OPTION_NO_BORING_EXPANSION` configuration macro.
This gives users a possibility to deactivate new features not (yet) in the
OpenType standard.

* include/freetype/config/ftoption.h, devel/ftoption.h
(TT_CONFIG_OPTION_NO_BORING_EXPANSION): New macro.

* src/truetype/ttgxvar.c (ft_var_load_avar): Use it to disable 'avar'
version 2.0 support.

Moazin Khatti 06c1a25e63 Add flag `FT_CONFIG_OPTION_SVG`.
This flag is going to be used to conditionally compile support for OT-SVG
glyphs.  FreeType will do the parsing and rely on external hooks for
rendering of OT-SVG glyphs.

* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_SVG): New flag.

David Turner 2f11522a2a Remove experimental auto-hinting 'warp' mode.
This feature was always experimental, and probably nevery worked
properly. This patch completely removes it from the source code,
except for a documentation block describing it for historical
purpose.

Werner Lemberg f999375a9a [GSoC] include/*.*, devel/*.*: Convert block comments to `light' style.
This second and final monster commit was created by applying Nikhil's

followed up by minor manual clean-up.

No change in functionality, of course.

Shao Yu Zhang f04d81751a [sfnt] Preliminary support of coloured layer outlines.
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.

If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead.  The current implementation
assumes that the foreground is black.

Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

There are still some issues with metrics; additionally, an API to
fetch color layers is missing.

Alexei Podtelezhnikov 410f3799b6 [smooth] Harmony LCD rendering.
This is a new technology for LCD-optimized rendering. It capitalizes
on the fact that each color channel grid is shifted by a third of a
pixel.  Therefore it is logical to render 3 separate monochrome
bitmaps shifting the outline by 1/3 pixel, and then combine them.
Importantly, the resulting output does not require additional LCD
filtering.

[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
rendering.

Werner Lemberg 08fd250e1a [pcf] Make long family names configurable.
The change from 2016-09-29 was too radical (except for people using
the openSuSE GNU/Linux distribution).  To ameliorate the situation,
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES gets introduced which controls
the feature; if set, a new PCF property option
`no-long-family-names' can be used to switch this feature off.

* include/freetype/config/ftoption.h, devel/ftoption.h
(PCF_CONFIG_OPTION_LONG_FAMILY_NAMES): New option.

* include/freetype/ftpcfdrv.h: New header file (only containing
