The '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 '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
'GI.Pango.Objects.EngineShape.EngineShape' implementation to handle shaping Arabic
for Fontconfig-based backends.
