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.
