When a model is sortable, but the the column is not currently used
for sorting, we want to reserve the space for showing the sort
indicator. But we currently set the icon to 'missing-image', which
is not great to show all over the place. So, just set the opacity
to 0.
With the keybinding, it is possible that users may trigger the
inspector unintentionally. Show a dialog that informs them about
whats going on and gives them a chance to back out.
The warning dialog can be bypassed with the
org.gtk.Settings.Debug inspector-warning setting.
Update visual.c to use Windows themes rather than the stock Raleigh theme,
and avoid hardcoding data paths for Windows (and Mac). As the dlfcn.h
functions are only used when Python is enabled, move its inclusion there[*].
Also ensure that variables are declared on the top of the block.
[*] Python support Windows needs to be investigated, as POSIX signal
handling is used there.

Since you can't take grabs on unmapped windows, GtkMenu takes a grab on
the menu in a convoluted way: it first grabs another window, shows the
menu window, and then transfers the grab over to the GtkMenu widget.
For normal menubars, this is perfectly fine, as the first window it grabs
is our toplevel, and that gets picked up in our transient path. For
GtkMenuButton or other spurious uses of gtk_menu_popup, it creates a new
temporary input-only window which it takes the grab on, known as the "grab
transfer window". Since this window isn't a transient-for of our new menu
widget window, the grab isn't noticed when we go to show it, and thus the
menu ends up as a new toplevel.
Add a special hack to GtkMenu and the Wayland backend which lets us notice
this "grab transfer window", and include it in our grab finding path.
It's sort of terrible to have to hack up the widgets instead of just the
backend, but the alternative would be an entirely new window type which is
managed correctly by GDK. I don't want to write that.
The entire UI is constructed with templates, so the wrapper
constructors are never called, except for gtk_inspector_window_new,
which gets called from the GTK+ code.
Show the actions that are added to GtkApplication and
GtkApplicationWindows, as well as action groups that are
inserted elsewhere with gtk_widget_insert_action_group.

Moving the inspector into libgtk lets use reuse internals without
having to add public API for everything or inventing awkward private
call conventions.

Add two new icon lookup flags, GTK_ICON_LOOKUP_DIR_LTR and _RTL,
which tell GtkIconTheme to look for icon variants which have a
-ltr or -rtl suffix. GtkIconHelper adds these lookup flags when
looking up icons.
Note that due to the way this overlaps with symbolic icon lookup,
directional variants of symbolic icons must be called -symbolic-rtl, not
-rtl-symbolic.

Provide API to query the matrix instead of API that applies the matrix
directly. This makes the API more flexible.
See the commits implementing shadows.
