Alexei Podtelezhnikov 7b73cb0707 [smooth] Formalize Harmony LCD rendering.
This generalizes magic outline shifts that make Harmony LCD
rendering work in terms of precise two-dimensional RGB subpixel
positions. These coordinates are now set in time of the `smooth'
module initialization and later used to shift a glyph outline for
rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same
coordinates. The letter, however, rotates them before using.
The LCD bitmap padding is also calculated using these coordinates.

* include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field
`lcd_geometry'.
* src/base/ftlcdfil.c (ft_lcd_padding): Reworked.
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly.

* src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]
(ft_smooth_init): Initialize `lcd_geometry'.
(ft_smooth_render_generic): Formalize outline shifts.

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.

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

* include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec,
