Log Message:
Update gtk3 to version 3.8.2
Rename patch-gtk_a11y_gail.c to patch-gtk_a11y_gtkaccessibility.c

Many improvements, bug fixes and translation updates:
https://git.gnome.org/browse/gtk+/tree/NEWS?id=3.8.2

Highlights:

* Deprecations and removals:
 - Custom CSS properties have been deprecated
 - Support for color schemes has been removed
 - gtk_style_provider_get_style, gtk_style_provider_get_icon_factory
 - GtkGradient and GtkSymbolicColor
 - All the padding style properties in menus

* CSS improvements:
 - Add cycle detection to color resolving

* A lot of filechooser button fixes

* The print dialog now shows printers that are discovered
  using avahi, if configured with --enable-avahi-browsing

* We now support the Window Manager frame synchronization protocol draft (when
  running under a WM that supports it). This means applications will throttle
  their drawing cycle to what the compositor is drawing, and the compositor
  will never render half-updated windows, for seamless resizing and improved
  smoothness in drawing.
  See https://mail.gnome.org/archives/wm-spec-list/2013-January/msg00000.html
  and the articles at http://blog.fishsoup.net/ for more details.

* We now support setting an opacity to any GtkWidget, not just toplevels:
  gtk_window_set_opacity has been deprecated in favor of gtk_widget_set_opacity.

* GtkIconTheme gained asynchronous loaders for GtkIconInfo objects

* GtkIconInfo has changed from being a boxed type to a GObject. This
  is technically an ABI change, but basically all existing code
  will keep working if its used as a boxed type, and its not
  possible to instantiate GtkIconInfos outside Gtk, so this is not
  expected to be a big problem.

* GtkTreeView and GtkIconView allow single-click activation

* GtkImage can be set from a resource

* GdkWaylandDisplay is now public

* gdk_window_set_fullscreen_mode: new function to let windows
  be fullscreened across multiple monitors

* We now use state flags for text direction: GTK_STATE_FLAG_LTR/RTL.
  gtk_style_context_set_direction() has been deprecated.

* We install headers for accessible implementations of GTK+ widgets.
  This makes it possible to implement accessibility for third-party
  widgets by subclassing the proper GTK+ implementation. To do this,
  include gtk/gtk-a11y.h.

* Invisible widgets now return a size of 0x0. This is an experimental
  change that makes GtkWidget::visible essentially behave the same way
  that "display: none" does in CSS. If you want the effect of CSS's
  "visibility: hidden", you can use a GtkNotebook with an empty page.

* GtkFrame now draws a background.

* The Broadway backend now installs a separate server: broadwayd.

* GtkBuilder now lets you refer to external objects from a ui
  file if the objects have been exported with the new function
  gtk_builder_expose_object()

* Font handling has been improved:
 - The default font is no longer handled like a custom style sheet
   that overrides everything, but as the initial value. This is the
   same behavior as in web browsers.
 - It is now possible to set font-family and font-size like other
   CSS properties, and relative font sizes are supported. Font
   sizes in CSS can be specified as numbers or with keywords
   like xx-small, medium, smaller, larger,...

* GTK+ now uses proper Unicode ellipses in strings.
