/* GTK+ - accessibility implementations
Make accessible implementations public This commit exposes the get_type() functions and standard headers for accessible implementations. This makes it possible to derive from the GTK accessible implementations without GType magic tricks. This is necessary, because we require the a11y type hierarchy to be parallel to the widget type hierarchy. So, if you derive a widget and need to adjust its a11y implementation, you have to be able to derive its accessible implementation. This commit probably exposes more than is absolutely necessary, it also exposes accessibles of widgets that are unlikely candidates for deriving from.

Fix inter-header includes Since we are going to install these headers soon, we need to make their mutual includes work in the installed location as well. Also, avoid including individual gtk headers, to avoid trouble with single-include guards.

a11y: Only emit signals when cells change; not upon creation This is a workaround for atspi-atk behaviour. atspi-atk uses signal emission hooks. So it to already catches signal emissions on creation of objects, before anyone could even think of g_signal_connect()ing. https://bugzilla.gnome.org/show_bug.cgi?id=746706
