-- Data type for holding a shaping plan.
-- 
-- Shape plans contain information about how HarfBuzz will shape a
-- particular text segment, based on the segment\'s properties and the
-- capabilities in the font face in use.
-- 
-- Shape plans can be queried about how shaping will perform, given a set
-- of specific input parameters (script, language, direction, features,
-- etc.).
