Theming code gets confused when computing the spacing for 0px wide dots
and then divides by 0. And then cairo complains and stops drawing
anything forever out of spite and then we end up with a single color
screen.

The window-dragging code had a number of issues: The code was
starting a drag on every button press, never bothering to cancel
them. This leads to the odd hand cursor occurring between the two
clicks to maximize. We relied on GDK's multi-click detection, which
gives us triple-clicks when we really want sequences of double-clicks.
Lastly, we didn't propery restrict double-click handling to the primary
button, so e.g. if you had a window on an empty workspace, double-right
click on the titlebar would maximize it, which is not intended.
This commit solves all three problem by a doing our own double-click
detection, and only starting a drag when the pointer goes out of
'double-click range'. We change the way dragging is implemented for
menubars and toolbars to just letting events bubble up, so they
get the same behaviour as the titlebar. To make this work, we
have to select for pointer motion events in a few more places.
The behaviour of gtk_text_view_add_child_in_window() used to be
quite broken. It scrolled with the window during scrolling, then
jumped to the absolute position when the widget resized. Furthermore,
in 3.10 we broke the first feature, making it always be fixed.
The "proper" way to handle this is to always follow scrolling. This
is what the only user so far (gedit) wants, and if you want some
kind of overlay you should use GtkOverlay instead.
So, this changes the behaviour to something that is internally consistent
and works. I.e. all added widgets scroll with the textview as needed.

Modify the tracker so that it manages the visibility of
GtkMenuTrackerItem by issuing insert and remove callbacks to the
user of the tracker.
This works by treating the GtkMenuTrackerItem as a virtual section which
contains 1 item when the item is visible and 0 items when it is hidden.
For efficiency reasons, we only employ this trick in the case that the
item has a hidden-when='' attribute set on it.
https://bugzilla.gnome.org/show_bug.cgi?id=688421
Add an internal API for checking if a GtkMenuTrackerItem is visible,
along with a signal for reporting changes in that flag. The item will
become invisible in situations according to the new hidden-when=''
attribute, which can be set to 'action-disabled' or 'action-missing'.
This new flag doesn't actually do anything yet, and none of the
consumers of GtkMenuTracker do anything with it (nor should they). A
followup patch will address the issue.
https://bugzilla.gnome.org/show_bug.cgi?id=688421
Refactor the code in the action observer remove function in order to
make way for the (efficient) handling of hiding of the item in the case
that hidden-when='' is given.

Strictly speaking, can_activate should always be set back to FALSE when
the action disappears from the muxer (since we can't activate it
anymore) but we forgot to do that.
This 'bug' could never cause a problem because 'can_activate' is never
directly queried for anything at all and the item would get marked
insensitive anyway. As soon as the action was re-added, can_activate
would be recalculated based on the new action before anything else could
happen.
All the same, this should be cleared here.

Remove a hash lookup from the separator sync logic (which is run every
time we change a menu). Instead, we do the lookup when creating the
section and cache the result.
This refactor will also help us in a future commit to add support for
hiding menu items based on missing actions.

This adds save/restore calls to the clear-to-transparent call in
the pixel cache, to avoid changing the default color of the
cairo_t. It also removes a call set_operator call that is no longer
necessary (it was trying to manually restore the state).

GtkApplicationWindow frees its internal action group on dispose for the
usual reasons: to avoid the possibility of reference cycles caused by
actions referring back to the window again.
Unfortunately, if it happens to be inside of a GtkActionMuxer at the
time that it is disposed, it will (eventually) be removed from the muxer
after it has been disposed. Removing an action group from a muxer
involves a call to g_action_group_list_actions() which will crash
because the internal action group to which we normally delegate the call
has been freed.
A future patch that reworks the quartz menu code will introduce a use of
GtkActionMuxer in a way that causes exactly this problem.
We can guard against the problem in a number of ways.
First, we can avoid the entire situation by ensuring that we are removed
from the muxer before we destroy the action group. To this end, we
delay destruction of the action group until after the chain-up to the
dispose of GtkWindow (which is where the window is removed from the
GtkApplication).
Secondly, we can add checks to each of our GActionGroup and GActionMap
implementation functions to check that the internal action group is
still alive before we attempt to delegate to it.
We have to be careful, though: because our _list_actions() call will
suddenly be returning an empty list, people watching the group from
outside will have expected to see "action-removed" calls for the
now-missing items. Make sure we send those. but only if someone is
watching.

A widget intended to offer contextual actions for a given view.
It allows packing children into the start or end as well as offering
a single centered child box.

Add gtk_tree_path_new_from_indicesv which takes an array of
integers with a length. Use "Rename to" annotation to rename the
method as gtk_tree_path_new_from_indices. This is needed because
the original method takes variadic arguments which is not supported
by introspection.

GtkMenuItemAccessible was assuming that an accel label is
always the immediate child of a menu item. It also did not
deal with manually set accels. Fix both of these.

Improve the color swatch accessible to set a proper role
depending on whether the swatch is selectable or not, and
set the checked atk state when appropriate.

The initial state of GtkModelMenuItem is that of a normal menu
item, but the accessible we are using, GtkCheckMenuItemAccessible,
starts out with a role of 'check menu item'. Fix that up by
explicitly setting the initial accessible role.
GtkModelMenuItem does not emit the ::toggled signal when a radio
item is activated, so listen for property notification for that
property. We still keep the ::toggled signal handler, in order
to not break other uses of check and radio menu items.
https://bugzilla.gnome.org/show_bug.cgi?id=720983
GtkModelMenuItem emits no property notification, since none of its
properties are readable. But the toggled property is just a proxy
for GtkCheckMenuItem::active, so we should ensure that property
notification is emitted for the ::active property.
Ensure the hscrollbar & vscrollbar at gtk_scrolled_window_add() time,
this allows one to subclass GtkScrolledWindow with templates and add
children, as this will happen at instance initialization time before
the construct adjustment properties take effect.
And update the colorchooser a11y test to a) use GtkColorChooser
instead of the deprecated GtkColorSelection and b) match this
change. Pointed out in
