Add gdk_device_get_last_event_window(), and use to implement the window
tracking we need for synthesizing crossing events for sensitivity changes
and gtk grabs, rather than keeping the information in qdata and updating
it based when GTK+ gets events.

Try to do a better job of keeping example content
from being too wide. It is often rendered as <pre>
text so the only time we can wrap it is in the source.
It is best to full break lines at all punctuation and
to try to keep the width under 70 chars or so.
The properties are declared read-write, but only the setter
was hooked up. This was leading to criticals in test apps using
the prop-editor.c code. Complete the implementation by adding the
getter side too.
Previously we did a semi-successful job at ignoring it. Unfortunately
this job was bad enough that we could lose the direction.
We still allow passing in the enum values, because we want code like
this to work:
set_state_flags (get_state_flags() | SOME_FLAGS)
10b5ec20 made sure not to set focus_child to NULL all the way up to the
top, but only up to the common ancestor. However, it would never set it
on the common ancestor itself, which would therefore remain with a
focus_child set when it shouldn't.
A manifestation of the bug: focus column headers of a treeview, press Tab.
Now pressing Shift+Tab will go to another widget and not the column
headers, and Tab will (appear to) do nothing, all because the treeview
still has a focus_child set to column headers after a grab_focus().

The root window is a fairly X-centric concept, and it
really has no place in the GtkWidget API. Plus, this
is a rarely-used one-line convenience function with
poor documentation.
Add margin-{start,end} and gtk_widget_{get,set}_margin_{start,end}
and drop margin-{left,right} and gtk_widget_{get,set}_margin_{left,right}.
margin-{start,end} handle right also in RTL.

_gtk_widget_draw_internal() was clipping by passing the subwindow
sizes as a path to cairo_clip(). This was breaking for windows
larger than 23 bits in width/height, due to cairo using fixed point
(24.8) for the path coordinates.
We fix this by pre-clipping the subwindow region to the existing
cairo clip region in the full 32bit gdkwindow precision. This fixes
the GooCanvas Large Items test.

For some widgets, like GtkTreeView, which setup a clock frame
update during realize, it was possible to call
gdk_frame_clock_begin_updating() twice, but only ever disconnecting
from it once. This happens because the realized flag is set at an
unpredictable time by the GtkWidget's realize implementation.
Keep the signal handler ID from us connecting to the "update" signal
to avoid connecting to it twice.
This fixes high wake-up count from any application using GtkTreeView,
even idle ones.

Previously, GtkWindow would add the "app" action group to its own
toplevel muxer.
Change the setup so that GtkApplication creates the toplevel muxer and
adds itself to it as "app". Use this muxer as the parent muxer of any
GtkWindow associated with the application.
This saves a small amount of memory and will allow for accels to be
propagated from the application through to all of the windows.
GtkWidget had a hack where if opacity is 0.999 we set up an opacity group when
rendering the widget. This is no longer needed in 3.10, and GtkStack doesn't
use it anymore.
GdStack is using it, so applications should be ported from GdStack to GtkStack
in 3.12.

Updated documentation to specify that '0' should be specified if
one does not need to automatically assign a bound child to a public
or private instance member (now that negative values are private
structure offsets).
* gtk/gtkwidget.c: drag-leave signal: Document that it is called before
drag-drop.
drag-data-received signal: Document that it is up to the application
to know why the data was requested (e.g. drag motion or drop).
* demos/gtk-demo/toolpalette.c: interactive_canvas_drag_drop():
Do not transform the drop_item created in the drag-motion handler.
Instead caused drag-data-received to be called, remembering why,
and create a new item there.
interactive_canvas_drag_leave(): Remove the idle-handler hack,
now that we do not need to keep the drag-motion drop_item alive until
the drop.
I noticed that this patch was sitting in bug #605611 from 2009
though it had been approved. I do not remember much about why I
created it.
This is the same behaviour as gtk_widget_get_valign, except
we have no gtk_wiget_get_halign_with_baseline, as baselines make
no sense for halign.
Without this some widgets (like e.g. GtkOverlay) crash if you accidentally
set a BASELINE halign.
We rename the gtk_widget_class_bind_template_child{_internal}
macros by appending a _private to their name. Otherwise, it
would be too magic to pass the 'public' names as arguments,
but affect a member of the Private struct. At the same time,
Add two new macros with the old names,
gtk_widget_class_bind_template_child{_internal} that operate
on members of the instance struct.
The macros and functions are inconsistently named, and are not tied to
the "template" concept - to the point that it seems plausible to use
them without setting the template.
The new naming scheme is as follows:
gtk_widget_class_bind_template_child_full
gtk_widget_class_bind_template_callback_full
With the convenience macros:
gtk_widget_class_bind_template_child
gtk_widget_class_bind_template_child_internal
gtk_widget_class_bind_template_callback
https://bugzilla.gnome.org/show_bug.cgi?id=700898https://bugzilla.gnome.org/show_bug.cgi?id=700896
Using an offset from the struct means you can have children in
both the public and private (via G_PRIVATE_OFFSET) parts of the
instance. It also matches the new private macros nicer.

We've recently a number of classes wholly. For these cases,
move the headers and sources to gtk/deprecated/ and adjust
Makefiles and includes accordingly.
Affected classes:
GtkAction
GtkActionGroup
GtkActivatable
GtkIconFactory
GtkImageMenuItem
GtkRadioAction
GtkRecentAction
GtkStock
GtkToggleAction
GtkUIManager
Historically the following states propagated to children:
GTK_STATE_FLAG_ACTIVE
GTK_STATE_FLAG_PRELIGHT
GTK_STATE_FLAG_SELECTED
GTK_STATE_FLAG_INSENSITIVE
GTK_STATE_FLAG_INCONSISTENT
GTK_STATE_FLAG_BACKDROP
However, several of these are problematic on containers like GtkListBox.
For instance, if a row is ACTIVE or SELECTED then all children (like e.g
a button) inside the row will *also* look active/selected. This is almost
never right. The right way to theme this is to catch e.g. SELECTED on the
container itself and set e.g. the color and let the children inherit
the color instead of the flag.
We now propagate only these flags:
GTK_STATE_FLAG_INSENSITIVE
GTK_STATE_FLAG_BACKDROP
Which make sense to be recursive as they really affect every widget
inside the container.
However, this is a CSS theme break, and while most things continue working
as-is some themes may need minor tweaks.
Rename our internal GActionMuxer, GActionObserver and GActionObservable
classes and interfaces to have names in our own namespace.
These classes were originally intended for GIO but turned out to be too
special-purpose to be useful there, so we never made them public API but
have just been copying them around (without bothering to properly rename
them). Now that other people will be copying them out of Gtk, it's even
more important to prevent this namespace abuse from spreading further.
This makes iterating over the children a lot faster, as we're
not doing lots of intra-library calls and type checks. We're still
in some sence O(n^2) since we iterate over each child window for each
widget, but the profiles look much better.
Since widgets now cache drawn state we allow them to override
queue_draw_region to detect when some region of the widget
should be redrawn. For instance, if a widget draws the
background color in a pixel cache we will need to invalidate
that when the style context changes which queues a repaint.
We do the save/restore when emitting ::draw rather than in a custom
marshaller, as this saves an extra stack frame, which is helpfull now
that we do painting fully recursive. This is also likely to save a few
cycles.
