Add a gtk_drag_cancel() function that can be used on the
source side to cancel an ongoing drag operation. This can
be useful, e.g. if the data that is being dragged becomes
unavailable.
Add helper for getting the main clipboard. This makes
the API usable for bindings (as GdkAtoms aren't usable through
gobject-introspection), and easier to use in C.

Add ::next-match, ::previous-match and ::stop-search keybinding
signals that are bound to Ctrl-g, Ctrl-Shift-g and Escape. Also
add a gtk_search_entry_handle_event() function to handle key events.
These functions, while added for use by the GTK inspector, are generally
useful to applications that need to resolve what action groups are
available to a particular GtkWidget.

Add a vfunc to return a non-scrollable border around scrollables.
This would be nicer as a property, but we can't add properties
to an interface without breaking 3rd party implementations, so
make this an optional vfunc, and handle it not being set.
This is not really needed. The gl context is totally tied to the
window it is created from by virtue of sharing the context with the
paint context of that window and that context always has the visual
of the window (which we already can get).
Also, all user visible contexts are essentially offscreen contexts, so
a visual doesn't make sense for them. They only use FBOs which have
whatever format that the users sets up.
This can be used by applications to indicate that a paned is expected
to be actively used by the users for configuring the UI, and needs
a prominent handle.

This is mostly useful for fallback testing.
I suppose if people want finer grained GL ability testing, they can use
Mesa environment variables to tune things.
This adds the new type GdkGLContext that wraps an OpenGL context for a
particular native window. It also adds support for the gdk paint
machinery to use OpenGL to draw everything. As soon as anyone creates
a GL context for a native window we create a "paint context" for that
GdkWindow and switch to using GL for painting it.
This commit contains only an implementation for X11 (using GLX).
The way painting works is that all client gl contexts draw into
offscreen buffers rather than directly to the back buffer, and the
way something gets onto the window is by using gdk_cairo_draw_from_gl()
to draw part of that buffer onto the draw cairo context.
As a fallback (if we're doing redirected drawing or some effect like a
cairo_push_group()) we read back the gl buffer into memory and composite
using cairo. This means that GL rendering works in all cases, including
rendering to a PDF. However, this is not particularly fast.
In the *typical* case, where we're drawing directly to the window in
the regular paint loop we hit the fast path. The fast path uses opengl
to draw the buffer to the window back buffer, either by blitting or
texturing. Then we track the region that was drawn, and when the draw
ends we paint the normal cairo surface to the window (using
texture-from-pixmap in the X11 case, or texture from cairo image
otherwise) in the regions where there is no gl painted.
There are some complexities wrt layering of gl and cairo areas though:
* We track via gdk_window_mark_paint_from_clip() whenever gtk is
painting over a region we previously rendered with opengl
(flushed_region). This area (needs_blend_region) is blended
rather than copied at the end of the frame.
* If we're drawing a gl texture with alpha we first copy the current
cairo_surface inside the target region to the back buffer before
we blend over it.
These two operations allow us full stacking of transparent gl and cairo
regions.
This is a new function that gets called every time we're drawing
some area in the Gtk paint machinery. It is a no-op right now, but
it will be required later to keep track of what areas which
we previously rendered with GL was overwritten with cairo contents.
This is a convenient shortcut for a common case. It is implemented
by adding a .monospace style class to the text view, and letting
the theme decide about the monospace font to use.
GtkSidebar behaves internally much like GtkStackSwitcher, providing a vertical
sidebar like widget. It is virtually identical in appearance to the widget
currently used in GNOME Tweak Tool.
This widget is connected to a GtkStack, and builds its own contents as a
GtkListBox subclass, using the "title" child property to provide a consistent
navigatable widget.
Being a subclass of GtkListBox it benefits immediately from strong keyboard
navigation, and minimal changes are required for theming.

Since it turns out that x/yalign can't be quite equivalently
replaced by h/valign, bring them back as label properties, so
we can eventually get rid of GtkMisc.

- Move the class to the Deprecated section.
- Warning at the bottom of the class description.
- A missing property was not marked as deprecated.
- Update doc of gtk_container_set_border_width() to not mention
GtkAlignment.

GtkStatusIcon is using a problematic, XEmbed-based protocol under X,
and we want to get rid of it eventually. Document our intentions by
marking GtkStatusIcon as deprecated.

At the present time broadway listens only for TCP/IP incoming
display connections. This patch implements the support for listening
on unix domain sockets too, adding the broadway_server_on_unix_socket_new()
constructor and the commandline option --unixsocket [path] to broadwayd.

This counterpart to gtk_application_get_accels_for_action() lets you
find out if a particular accelerator has one or more actions associated
with it. This might be useful from an accelerator editor or plugin
system to prevent the the installation of conflicting accelerators.

Having an explicit property for this will make it easier
to have a hover style only for rows which are activatable
or selectable.
Rows are selectable by default, to preserve compatibility.
This will let us theme activatable rows differently.
We also avoid emitting the ::row-activated signal for
rows that are not activatable. For compatibility reasons,
rows are activatable by default.

Resize grips were introduced for GNOME 3.0, before we had any of the
"new GNOME app" features like invisible borders and CSD. With OS X 10.6
and 10.7, Apple has replaced the classic grips in their applications
with invisible borders as well.
New GNOME app designs don't use resize grips anymore and the new
default theme for GTK+, Adwaita, disables them entirely by forcing their
width and height to 0.
They're past their time. Remove the code to support them. This can
always be reverted if some app relies on them.
Applications can call this to determine if they should an app menu.
This will be %FALSE on desktop environments that do not have an
application menu like the one in gnome-shell. It is %FALSE on Windows
and Mac OS.
Applications are completely free to totally ignore this API -- it is
only provided as a hint to help applications that may be interested in
supporting non-GNOME platforms with a more native 'look and feel'.

This makes it possible to look up icons in resources using
the icon theme api, and should be used as a replacement
for installing icons below $pkgdatadir/icons and adding
that location to the search path.
