[Pkg-ime-devel] IBus: Surrounding Text Support

[Harshula]

The essential input methods that use Surrounding Text Support, such as
si-wijesekera.mim (m17n), have the ability to fallback to pre-edit when
STS is not available. Hence, they will work correctly with applications
that do not support STS.
