This work was Anuj Verma's GSoC 2020 project.
+ - A new, experimental API is now available for surfacing properties
+ of 'COLR' v1 color fonts (as the name says, this is an extension
+ to the 'COLR' table for outline color fonts using the SFNT
+ container format). 'COLR' v1 fonts are a recently proposed
+ addition to OFF and OpenType; specification work currently happens
+ in
+
+ https://github.com/googlefonts/colr-gradients-spec/
+
+ 'COLR' v1 is expected to be merged to OpenType; the ISO
+ standardisation process for adding 'COLR' v1 as an amendment to
+ OFF is underway.
+
+ Functions similar to the already existing 'COLR' API have been
+ added to access the corresponding data.
+
+ FT_Get_Color_Glyph_Paint
+ Retrieve the root paint for a given glyph ID.
+
+ FT_Get_Paint_Layers
+ Access the layers of a `PaintColrLayers` table.
+
+ FT_Get_Colorline_Stops
+ Retrieve the 'color stops' on a color line. As an input, a
+ color stop iterator gets used, which in turn is retrieved from
+ a paint.
+
+ FT_Get_Paint
+ Dereference an `FT_OpaquePaint` object and retrieve the
+ corresponding `FT_COLR_Paint` object, which contains details
+ on how to draw the respective 'COLR' v1 `Paint` table.
