-- The t'GI.HarfBuzz.Structs.FeatureT.FeatureT' is the structure that holds information about requested
-- feature application. The feature will be applied with the given value to all
-- glyphs which are in clusters between /@start@/ (inclusive) and /@end@/ (exclusive).
-- Setting start to /@hBFEATUREGLOBALSTART@/ and end to /@hBFEATUREGLOBALEND@/
-- specifies that the feature always applies to the entire buffer.
