-- Performs measurements on paths such as determining the length of the path.
-- 
-- Many measuring operations require sampling the path length
-- at intermediate points. Therefore, a @GskPathMeasure@ has
-- a tolerance that determines what precision is required
-- for such approximations.
-- 
-- A @GskPathMeasure@ struct is a reference counted struct
-- and should be treated as opaque.
