Kinetic scrolling is only done on touch devices, since it is
sort of meaningless on pointer devices, besides it implies
a different input event handling on child widgets that is
unnecessary there.
If the scrolling doesn't start after a long press, the scrolling is
cancelled and events are handled by child widgets normally.
When clicked again close to the previous button press location
(assuming it had ~0 movement), the scrolled window will allow
the child to handle the events immediately.
This is so the user doesn't have to wait to the press-and-hold
timeout in order to operate on the scrolledwindow child.
The innermost scrolled window always gets to capture the events, all
scrolled windows above it just let the event go through. Ideally
reaching a limit on the innermost scrolled window would propagate
the dragging up the hierarchy in order to keep following the touch
coords, although that'd involve rather evil hacks just to cater
for broken UIs.
This patch adds a capture phase to GTK+'s event propagation
model. Events are first propagated from the toplevel (or the
grab widget, if a grab is in place) down to the target widget
and then back up. The second phase is using the existing
::event signal, the new capture phase is using a private
API instead of a public signal for now.
This mechanism can be used in many places where we currently
have to prevent child widgets from getting events by putting
an input-only window over them. It will also be used to implement
kinetic scrolling in subsequent patches.

We automatically request more motion events in behalf of
the original widget if it listens to motion hints. So
the capturing widget doesn't need to handle such
implementation details.
We are not making event capture part of the public API for 3.4,
which is why there is no ::captured-event signal.
We don't want to fallback for 'random' touch sequences, since
that could lead to all kinds of pairedness and other violations.
Since the X server already tells us what touch events it would
have used for emulating pointer events, we just use that information
here.
GtkButton currently draws itself as active (pressed down) in case we're
pressing and holding the mouse pointer outside its bounds; this is
misleading though, since we won't activate the button unless the mouse
is released inside the button itself.
Fix this by only setting the ACTIVE state flag when the button is
actually pressed down.

This does nothing but turn all GtkBitmask functions into static inline
functions that call the gtk_allocated_bitmask_*() equivalent.
The implementation of the static functions has also been put into a
private header, to not scare people who want to see how things are
implemented.
When we're allocating children of GtkOverlay, compare their allocation
with the overlay one, and set left/right/top/bottom style classes if the
overlaid widget touches one or more of the overlay edges.

gtk_widget_translate_coordinates() can fail in case the widget is not
realized or there's no common ancestor. Don't use the x/y values
returned by that method in that case, since their value is undefined.
If there's a junction between the two scrollbars (i.e. they're both
visible), draw a background with a style class there, so the theme can
style it.

If the display server or GDK hides the window - fire the "deactivate" signal
to ensure that the internal state is consistent.
This patch also ensures that the "deactivate" signal will not be fired for a
menu that is not active.

Since GtkCellRendererText moved to WFH requests, our get_size
implementation is ignored. We should override get_preferred_width
instead. This fixes the accel renderer being clipped to a wrong size
when trying to edit its shortcut.
This patch changes all uses of GDK_DEPRECATED(_FOR) in gtk headers
by the versioned variants, GDK_DEPRECATED_IN_3_x(_FOR). At the same
time, we add GDK_AVAILABLE_IN_3_x annotations for all API additions
in 3.2 and 3.4.
The message-type css classes must be in the widget context all the time,
not only when drawing, otherwise they are not propagated to the
children, for instance a label in the InfoBar must inherit the
color. Add a corresponding reftest.

The widget window is usually covered by the bin_window.
Its background color will become relevant when we introduce
kinetic scrolling with overshooting.

_gtk_widget_set_device_window() is suppose to make accounting of
the topmost widget under the device at each time, so avoid setting
it on virtual crossing events as the device is already in another
window.
The implicit grab on priv->event_window already warrants that this
widget is the only one getting events while the button is pressed,
so avoid the extra GTK+ grab here.
Store the device, and unset private fields whenever the device
is shadowed by another GTK+ grab, so popping up menus while
selecting (i.e. press-and-hold) doesn't leave the entry in a
confused state.
* Restores the old padding
* Prelight on spin buttons
* Don't have a generic prelight background selector, as that got
picked up by things like images that should have a transparent bg.
No need to subtract focus line width again, since the progressbar is
rendered starting at (0, 0).
This also fixes the entry-progressbar-coloring reftest.
Instead of firing a 'quit' signal and expecting the application to do
something that will cause it to quit, just call the new
g_application_quit() API for ourselves.

This seems a bit "too powerful" and unlikely to be used by most
applications. Remove it from now, until someone comes up with a strong
desire for it.
