* A bunch of new functions has been added to access and process
COLR/CPAL data of OpenType fonts with color-layered glyphs.
* As a GSoC 2018 project, Nikhil Ramakrishnan completely
overhauled and modernized the API reference.
* The logic for computing the global ascender, descender, and
height of OpenType fonts has been slightly adjusted for
consistency.
* `TT_Set_MM_Blend' could fail if called repeatedly with the same
arguments.
* The precision of handling deltas in Variation Fonts has been
increased.The problem did only show up with multidimensional
designspaces.
* New function `FT_Library_SetLcdGeometry' to set up the geometry
of LCD subpixels.
* FreeType now uses the `defaultChar' property of PCF fonts to set
the glyph for the undefined character at glyph index 0 (as
FreeType already does for all other supported font formats). As
a consequence, the order of glyphs of a PCF font if accessed
with FreeType can be different now compared to previous
versions.
This change doesn't affect PCF font access with cmaps.
* `FT_Select_Charmap' has been changed to allow parameter value
`FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
formats to access built-in cmaps that don't have a predefined
`FT_Encoding' value.
* A previously reserved field in the `FT_GlyphSlotRec' structure
now holds the glyph index.
* The usual round of fuzzer bug fixes to better reject malformed
fonts.
