    Description

      The COLR/CPAL color font format is supposed to be supported by Freetype in more recent versions, but for some reason, we only get black/white glyphs from this in Qt. Most likely there is specific API to render the different layers, like on DirectWrite, so this is something that needs to be handled manually in the code.
