-- The t'GI.Pango.Objects.EngineShape.EngineShape' class is implemented by engines that
-- customize the rendering-system dependent part of the
-- Pango pipeline for a particular script or language.
-- A t'GI.Pango.Objects.EngineShape.EngineShape' implementation is then specific to both
-- a particular rendering system or group of rendering systems
-- and to a particular script. For instance, there is one
-- t'GI.Pango.Objects.EngineShape.EngineShape' implementation to handle shaping Arabic
-- for Fontconfig-based backends.
