It's been long enough. We can mandate support for these, at least
at build-time. The code doesn't actually compile without either
of these, so just consider that unsupported.
This has one regression: the basic touch support added by
Carlos Garnacho in 991c85f is now partially reverted, since
we ported to Clutter events for this. We'll need to either
port his changes to Clutter, or restructure event handling
in mutter directly.
We can't really support the Gtk+ automatic scaling, as to much
code relies on the GdkWindow and XWindow sizes, etc to match.
In order to keep working we just disable the scaling, meaning
we will pick up the larger fonts, but nothing else. Its not
ideal but it works for now.

The reason we don't simply use gdk_window_add_filter directly is
because of some twisted idea that any GDK symbol being used from
core/ is a layer violation. While we certainly want to keep any
serious GDK code out of ui/, event handling is quite important
to have in core/, so simply use a GDK event filter directly.
Currently touch events are ignored in the core event handler,
and hence dealt with within GDK. If those touch events were
emulating pointer events, GDK would attempt to convert back
those events to pointer events as the frame GdkWindow doesn't
have the GDK_TOUCH_MASK set.
This results in XI_TouchBegin events being initially processed
by GDK, converted to button events, and triggering a grab op
that subverts touch events into pointer events, so the touch
is never ever seen again by GDK. This leaves GDK in an
inconsistent internal state wrt pointer grabs, so future
pointer-emulating touches will refer to the same window forever.
Fix this by handling touch events minimally, just enough to
convert XI_TouchBegin to GDK_BUTTON_PRESS within mutter, so GDK
is bypassed for every touch event just like it is for pointer
events. This, and the XIGrabDevice() that keeps coercing pointer
events when the grab operation starts, are enough to fix window
drag and drop on touch devices.

Since the introduction of frame sync in GTK+, updates to titlebar font and
colors haven't been working because GTK+ counts on the frame clock to
do style updates, and the frame clock doesn't run for an unmapped
GdkWindow. (It's possible that GtkStyleContext changes subsequent to
the introduction of the frame clock were also needed to fully break
things.)
We actually need to map the MetaFrames GdkWindow and let the
compositor code send out the frame sync messages in order to pick up
style changes.
Hopefully no bad side effects will occur from this - we make the window
override-redirect, 1x1, and outside the bounds of the screen.

Switching meta/util.h to gi18n.h was wrong, mutter is a library
and needs gi18n-lib.h, but that cannot be included from a public
header (since it depends on config.h or command line options),
so split util.h into a public and a private part.

Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.
Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

g-ir-scanner will emit more warnings regarding broken GTK-Doc

This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".
The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

A correctly constructed GtkStyleContext must have its screen
and widget paths set. Getting the frame font caused crashes
on some systems because those were not correctly initialised.

- set GTK_STYLE_CLASS_TOOLTIP on the window, and use the same code of
GtkTooltip to paint it
- set GDK_WINDOW_TYPE_HINT_TOOLTIP and make the window non-resizable, so
it doesn't get an incorrect shadow from the WM
https://bugzilla.gnome.org/show_bug.cgi?id=692741
Since we're going to use the tooltip's rounded corners we need a little
bit more of margin (which wasn't a bad idea even with the frame).
Also, don't use GtkMisc for this anymore.

GtkWindow added the BACKGROUND style class to all windows, which the
CSS file selects on to set a background color for all windows. Without
this, the background color becomes undefined, and thus window frames
look like they have "glitchy" graphics.

The style context of the widget is rarely what we want. We won't
fix this to be a MetaFrames style context yet; this just changes
the internal API.
