Overview of Changes from GTK+ 2.91.6 to 2.91.7
==============================================

* The treeview-refactor branch has been merged, bringing more
  flexible cell arrangement with GtkCellArea, GtkCellAreaBox, etc

* The gdk-backend branch has been merged. This branch cleans up the
  internal frontend/backend separation in GDK, with the ultimate goal
  of allowing to build a single gdk library that contains multiple
  backends (interesting combinations are x11+wayland or quartz+x11).

  For now, GDK is still restricted to a single backend, but
  as a first step, the libraries no longer include the backend name
  in their soname, but are just libgdk-3.0.so and libgtk-3.0.so.

  Only the x11 backend has been kept up to date with this cleanup
  work, other backends are broken in this release.

* Deprecations and removals:
 - G_SEALed struct members have been removed from GtkWindowGroup,
   GtkDrawingArea, GtkTreeStore, GtkTreeModelSort, GtkTreeSelection,
   GtkSocket, GtkPrintJob, GtkSelectionData
 - Input device handling:
   - gdk_display_list_devices, gdk_display_get_core_pointer,
     gdk_input_set_extension_events, gtk_widget_set_extension_events,
     gdk_devices_list have been removed
   - gdk_display_warp_device has been replaced by gdk_device_warp
   - gdk_enable_multidevice has been replaced by gdk_disable_multidevice
 - Drag-and-Drop:
   gdk_drag_context_new, gdk_drag_find_window and gdk_drag_get_protocol
   have been removed
 - Property handling:
   Functions that deal with X11-specific encodings such as Compound Text
   have been moved to backend-specific API:
   gdk_string_to_compound_text[_for_display],
   gdk_utf8_to_compound_text[_for_display], gdk_free_compound_text,
   gdk_text_property_to_text_list[_for_display], gdk_free_text_list,
   gdk_text_property_to_utf8_list
 - Foreign windows:
   Functions for dealing with GdkWindow wrappers around foreign
   windows have been moved to backend-specific API.
 - Application launching:
   The gdk_spawn_* APIs have been removed, since they were trivial
   wrappers around g_spawn_* on most platforms and can be replaced
   by GIO GAppInfo APIs.
 - Misc. other functions: gdk_net_wm_supports, gdk_set_locale,
   gdkx_visual_get have been either removed, gdk_set_sm_client_id
   has been moved to backend-specific API.

* A number of GTK+ widgets have been ported to use GtkStyleContext
  directly for rendering

* The tracker search backend for the file chooser has been updated
  to work with libtracker-sparql as available in tracker >= 0.9

* The GtkAboutDialog has been given a facelift. It no longer
  opens second-level dialogs

* The GDK X11 backend now uses XI2 (including multi-device capabilities)
  by default. Use gdk_disable_multidevice() to switch back to the
  XI1/Core implementation
