Applications that provide accessibility through the ATK interfaces need a way
to translate those interfaces to AT-SPI2 DBus calls. This module, at-spi2-atk,
provides that translation bridge.
Several things use at-spi2-atk:
* GTK3 calls ATK directly and assumes that at-spi2-atk is backing it.
* GTK2 loads a module at runtime to do the same (atk-adaptor/gtk-2.0 in this module).
* Chromium.
* Gnome-shell.
* Any applications that use ATK directly, like Mozilla Firefox, will need at-spi2-atk
backing them.
