-- A @PangoGlyphVisAttr@ structure communicates information between
-- the shaping and rendering phases.
-- 
-- Currently, it contains cluster start and color information.
-- More attributes may be added in the future.
-- 
-- Clusters are stored in visual order, within the cluster, glyphs
-- are always ordered in logical order, since visual order is meaningless;
-- that is, in Arabic text, accent glyphs follow the glyphs for the
-- base character.
