Shorten test paths
Split GtkWindowGroup into its own file

gtkwindow.c is too big and too messy. This is a small step
towards making it better.
Fix up internal function naming

Even if you believe this functionality belongs into gdk, it
is not ok to name internal functions in gtkwindow.c gdk_window...
widget: Set GDK_BUTTON1_MASK on emulated pointer events

The touch_event handler was missing those when emulating pointer events
for the widgets that get GDK_TOUCH_MASK set, but have no specialized
touch handlers.
tests: Add multitouch gesture tests

So far, gesture behavior on lack/excess of touchpoints is tested, as well
as sequence hand-in between gestures in these situations.
inspector: Go to the desired tab

We were setting the next-tab properly, but were trying to
read it off the wrong object. Now, going from a cell renderer
attribute mapping to the model, or from an action-name to the
action actually works.
inspector: Show the widget tree when picking

Makes more sense that way.
inspector: Lower the inspector window when picking

This avoids the problem  of the inspector window covering the
widget you want to pick.

gtk/deprecated/gtkcolorsel.c: Include gtkwindowgroup.h

Since commit 872fbfac the GtkWindowGroup was split out from the GtkWindow
sources, so include gtkwindowgroup.h to avoid C4013 warnings/errors
(implicit declaration of ...) on gtk_window_group_add_window().
inspector: Add an initial action editor

Use a popup, like we do for properties. For now, it allows
activating the action (with parameter, if necessary) and
setting the state.
inspector: Fix a memory leak
inspector: Actually destroy the property editors

We were never finalizing any of the popovers used for editing
properties. Fix that.
Updated Hebrew translation
GtkMenuTracker: fix signal handler argument list

The signal handler for the visibility of menu items changing had the
wrong signature, resulting in the GParamSpec from the notify signal
being treated as a boolean (which was always true).  This resulted in
items being added over and over and never being removed.

Fix that...
inspector: show GMenus

This does not quite work yet, and I have no idea why.
Forgotten file
inspector: Make GMenu content show up

My problem was that all the content is usually hidden away
in sections, so without recursion, nothing shows up. So,
implement the recursion then.
widget: reset all controllers when the widget becomes insensitive

Widgets becoming insensitive won't receive further events, but there
could be chances the controllers don't get properly notified and reset
in those situations.
expander: Use multipress gesture for event management

This actually acts regardless of the value n_press, alternatively
expanding and collapsing the GtkExpander.
