PangoEngineLangClass:
@script_break: Provides a custom implementation of pango_break().
If %NULL, pango_default_break() is used instead. If not %NULL, for
Pango versions before 1.16 (module interface version before 1.6.0),
this was called instead of pango_default_break(), but in newer versions,
pango_default_break() is always called and this is called after that to
allow tailoring the breaking results.
