Overview of Changes from GTK+ 2.91.1 to 2.91.2
==============================================

* GtkApplication has been rewritten. It mostly relies on GApplication
  API now. Remaining functions include gtk_application_new() and
  gtk_window_set_application()

* A GtkScrollable interface has been added and implemented by all
  scrollable widgets. GtkScrolledWindow has ::min-display-width/height
  properties to control the minimal size of the content area.

* GtkComboBox changes:
 - Popups can be wider than the combo box itself
 - The deprecated GtkComboBoxEntry subclass has been removed
 - The deprecated combo box text convenience API has been removed

* GtkRecentManager changes:
 - Store xbel file in XDG_USER_DATA
 - Add gtk_recent_info_create_app_info()
 - Add gtk_recent_info_get_gicon()
 - Coalesce multiple changes

* GtkIconView allows tree models (ignoring anything below the root level)

* GtkProgressBar, GtkSpinButton, GtkEntry and GtkCalendar no longer have
  their own input-output window

* gtk_widget_hide_all() has been removed

* GtkGrid: A legacy-free, height-for-width grid container

* GDK gained a GdkRGBA color struct containing 4 doubles, and various
  GdkColor APIs have GdkRGBA counterparts now.
