The EngineShape
class is implemented by engines that
customize the rendering-system dependent part of the
Pango pipeline for a particular script or language.
A 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
EngineShape
implementation to handle shaping Arabic
for Fontconfig-based backends.
Synopsis
