* Change some error return values to match AT-SPI-CORBA behavior.

* Some attribute-related fixes.

* Renamed 'text' to 'content' in AtspiTextRange to match original IDL.

What's new in at-spi2-core 1.91.3:

* Added a C-based AT-side binding (libatspi) which can be used in
  conjunction with GObject introspection to generate bindings for other
  languages.  However, this release has many bugs and is more of a development
  snapshot than a usable release.

What's new in at-spi2-core 1.91.2:

* The desktop object now returns ROLE_DESKTOP_FRAME rather than ROLE_UNKNOWN.


What's new in at-spi2-core 1.91.0:

* --disable-relocate is the default again.

What's new in at-spi2-core 0.3.92:

* Do not start accessibility bus if at-spi-corba is enabled.

What's new in at-spi2-core 0.3.91:

* Enabled the accessibility bus, so apps should be accessible, for instance,
if an application becomes setuid root.

* Several build fixes.

* Default to --enable-relocate for now.

What's new in at-spi2-core 0.3.90:

* FDO#29427: Registering for mouse:abs now works.

* Add methods/signals to allow an application to track the events that are
being listened to to avoid unnecessarily emitting signals.

What's new in at-spi2-core 0.3.4:

* Added GetChildren to the spec.

What's new in at-spi2-core 0.3.3:

* Add return values to some functions that were missing them.

* Make DeviceEventListener notifiers reentrant so that an application can
query the desktop object while processing a device event.

* Fix for FDO#28300: fails to link with pedantic linkers.

* Fix crash if GetChildAtIndex is called with an invalid index.

What's new in at-spi2-core 0.3.2:

* Make sure that disconnecting applications send their root path in the
remove applications signal. This was causing applications to not be
removed from the desktop properly.

What's new in at-spi2-core 0.3.1:

* Set an application's Id when registering it.

* Disabled relocation by default.
