We have been ignoring those buttons since 3.16 after they had been
broken in the default theme for a couple of versions. As nobody
appears to miss them, it's time to remove them for good.
We can get this operation in some cases, for example when
we're trying to resize window that cannot be resized.
This can occur with maximized windows that have a border
(without border we couldn't resize them by mouse in maximized state).
In this case we reached abort() beacuse we did not handle this op.

As we opt out of GTK+/Clutter's HiDPI handling, we need to apply the
window scaling factor manually to decorations, both the geometry and
when drawing.

We're locked to frame sync anyway, so it doesn't make sense to try to
redraw early. In casual testing, this seems to actually make things
faster, as well.
Break down the beautiful core/ui abstraction barrier by inserting
a pointer to MetaWindow into a MetaUIFrame. I'm a scoundrel, I know.
We'll use this very soon to destroy meta_core_get.
Whenever we added a frame to the GHashTable, we added the frame itself
as the value, and a pointer to its storage of the frame window XID,
as the key.
When we iterated over the hash table, we actually looked up the
MetaUIFrame in the key, which might seem extraordinarily wrong, but
eagle-eyed viewers might notice that the XID is the first field in
MetaUIFrame, so the key and value are actually the same pointer.
Changing the layout of MetaUIFrame at all causes this to go haywire,
so let's not do this and simply put the MetaUIFrame in the value,
as expected.
When the frame type updates, we were doing something funky that
caused us to reset the title used for the text layout here. I can't
really think of any place that it would trigger, and in testing I
haven't hit this either, so let's just remove the fancy logic and
assert this.
MetaFrameStyle now only holds a MetaFrameLayout, so we can cut out
the middle man and use the layout directly. And as we are already
using a single style/layout per frame set and handle frame state
and focus by setting appropriate style flags, MetaFrameStyleSet
is pointless too - just store one MetaFrameLayout per frame type
directly in the theme.

The frame shape is relevant in three places:
- the window decoration we draw
- the frame mask (used for the shape region)
- the frame bounds (used for clipping)
All three should match, so make sure to use the same GTK+ method for
the first two, and bring the (non-antialiased) third closer to the
other two by removing an obscure modifier from the corner radius.

We now have everything in place to pick up geometry and drawing
information from GTK+ rather than the metacity theme, so do just
that; the metacity theme is now only used for some constants
(title_scale, hide_buttons, ...), which we will replace soon.
https://bugzilla.gnome.org/show_bug.cgi?id=741917
Sounds obvious, doesn't it?
After this change when titlebar-uses-system-font is set, the "system
font" used will not be a generic one, but match what GTK+ uses in
client-side decorations.

Our current use of style contexts is fairly limited - we don't
use them for much more than picking up some color information.
We will soon start to make more elaborate use of GTK style
information, but a single context will no longer be enough
to draw a frame then.
To prepare for this, add a simple ref-counted type to wrap
style information.

This way the xserver never paints the frame background, even if
the client window is destroyed. This allows us to have clean
destroy window animation.
There is no problem with interactive resizing because applications
are using the XSync protocol, so we're not painting unless the
client has redrawn.

When a passive touch grab is rejected over the frame, management is punted to
the frame itself, and pointer events emulated, but the attempt to transfer the
grab from the GDK connection to the Clutter one fails with AlreadyGrabbed, and
will fail until the Clutter connection receives the XI_TouchEnd resulting from
XIRejectTouch, gotten after the XI_ButtonPress on the GDK connection.
In order to bypass this shortcoming, store the current grab operation on the
frame as long as the button is pressed, so it is retried once on the next
motion event happening during frame dragging, that will have a recent enough
timestamp to succeed. If no grabbing succeeded, the current grab operation
data will be reset on GDK_BUTTON_RELEASE.
Since GTK+ already clips to the extended region for us, there's no need
to combine the two. This does lose the fast-path, but I don't actually
expect this to fire, as when we're composited, we really won't ever get
partial exposes.
mutter is quite bad at using GTK+ correctly, relying on dumb things
like the single-buffering stuff. Hack up a temporary fix for the
newer GTK+ rendering changes.
prelit_control is used for both prelight and pressed states, so the early
return in update_prelit_control() misses the case where prelit_control
already matches the control we are updating, but its state is PRESSED
rather than PRELIGHT. Fix the condition to not have pressed controls
linger around erroneously.

Since window menus have been moved to the compositor, the pressed
state of the corresponding window buttons is messed up, as it is
reset immediately when getting a LeaveNotify event due to the
compositor taking a grab. Fix this by ignoring that particular
event.

When opening the window menu without an associated control - e.g.
by right-clicking the titlebar or by keyboard - using coordinates
for the menu position is appropriate. However when the menu is
associated with a window button, the expected behavior in the
shell can be implemented much easier with the full button geometry:
the menu will point to the center of the button's bottom edge
rather than align to the left/right side of the titlebar as it
does now, and the clickable area where a release event does not
dismiss the menu will match the actual clickable area in mutter.
So add an additional show_window_menu_for_rect() function and
use it when opening the menu from a button.
