Grab operations are now always taken on the backend connection, and
this breaks GTK+'s event handling.
Instead of taking a grab op, just do the handling ourselves. The
GTK+ connection will get an implicit grab, which means pointer /
keyboard events won't be sent to the rest of mutter, which is good.
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.

Mutter previously defined display->focus_window as the window that the

Make MetaDisplay do a better job of tracking focus-related requests

the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

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.

This patch also introduces a macro named USE_GTK3 that is used to
differentiate between GTK3 and GTK2. Its main use is differenting
between expose and draw handlers for GtkWidget subclasses.
The draw vs expose handlers question is usually handled by using ifdefs
at the beginning and end to set up/tear down a cairo_t and then use it.

meta_gdk_pixbuf_get_from_pixmap() as that function will need special
treatment in GTK3 anyway.

Rename meta_frames_paint_to_drawable() to meta_frames_paint() and make
it take a cairo_t as an argument instead of creating the cairo_t itself.
This patch refactors code for GTK3 changes where code needs to handle
cairo_t and not GdkDrawable arguments.

This commit is in preparation for the work happening in GTK3, which will
use Cairo for drawing exclusively. So it is necessary to move all
drawing code to Cairo. In this commit the "gtk2" code is used for both
gtk2 and gtk3; compatibility with newer versions of gtk3 where different
code is needed will be added subsequently.
For compatibility with older GTK versions, the file gdk2-drawing-utils.h
provides a compatibility layer.
The commit changes the API of libmutter-private.

The widget needs to be visible and mapped for GTK3 to deliver expose
events to the widget. This is achieved by making the map function a
no-op and calling gtk_widget_show() instead of just calling
gtk_widget_realize().
Apart from making GTK think the widget is drawable, the effect is the
same.

This way, we can remove the special casing in
meta_frames_paint_to_drawable().
Since the setup in meta_frames_paint_to_drawable() is relatively cheap,
doing it once per rectangle in the expose area should be fine.

gtk_rc_get_style_by_paths() returns NULL if no matching style was
found and the default style should be used. Actually use the default
style in this case.

When dragging a window over a screen edge and dropping it there,
maximize it vertically and scale it horizontally to cover the
corresponding half of the current monitor.
Whenever a "hot area" which triggers this behavior is entered, an
indication of window's target size is displayed after a short delay
to avoid distraction when moving a window between monitors.

Cleanly build with --warn-fatal. Implementation:
* Liberally apply (skip) where the API is clearly C only, e.g. uses
XLib. The theming code and MutterPlugin are skipped too.
* Add missing (transfer) and (element-type) annotations
For a few functions that had a comment, I turned it into gtk-doc, but
I didn't (with a few exceptions) try to write new documentation in
this pass.
The gdk_window_get_background_pattern() function copied from GDK and
introduced in commit 0839c10 has a small syntax error and uses a private
API (_gdk_drawable_ref_cairo_surface()). This patch imports the missing
API and fixes the syntax error.

gdk_window_get_back_pixmap() and gdk_window_get_background() have
been removed/deprecated. Use gdk_window_get_background_pattern()
as replacement.

In order to replace calls to deprecated GDK code, the current
development version of GTK+ is required. Add some basic compatibility
code to allow building mutter with GTK+ 2.18.
https://bugzilla.gnome.org/show_bug.cgi?id=587991
To replace all calls to deprecated code, GTK+ 2.20 is required - add
some basic compatibility code, so that it is still possible to build
mutter with GTK+ 2.18 when not using -DGSEAL_ENABLE.
