For reasons related to interaction between the GTK+ CSS code and the
frame sync protocol, the dummy GtkWindow that MetaUI creates to track
theme properties has to be mapped and have MetaWindow associated with it.
Add a private function so that the test framework can filter this out.

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.
Designers got used to RGBA support in GTK+, so the colors we pick
up from there might well have an alpha channel; update our gradient
rendering to support this - eventually we should probably port that
code to cairo ...
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.
While the comment claims that we may want to keep this around
for optimization purposes, the operations are raw bitmap operations
that would be cleaner done in cairo.

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.

We have two different coordinate spaces here. One is the rectangle
returned by meta_window_get_frame_rect, which is called the "frame
rect" or "the window geometry", which includes visible frame borders
but not invisible frame borders. The other is "frame->rect" which
corresponds to the frame's server geometry. That is, it includes
both visible and invisible frame borders.
These two were of course the same until we introduced invisible
frame borders, and an executive decision was made to make
meta_window_get_frame_rect return the rectangle bounding the
visible portions of the frame.
As time went on, the "frame rect" turned out to be more useful when
making decisions upon, since the user often doesn't think about the
invisible window geometry as part of the window.
We already calculate what amounts to the "frame rect" in the theme
code, so just change META_CORE_GET_FRAME_RECT to consume that
directly.
Since we're going to be calling meta_window_get_frame_rect in here
soon, I'd rather it be one method call, rather than two. We can't
put it at the toplevel, since that might cause infinite recursion
(e.g. meta_core_get calls meta_window_get_frame_rect calls
meta_ui_get_frame_borders calls meta_core_get, ...)
The last commit added support for the "appmenu" button in decorations,
but didn't actually implement it. Add a new MetaWindowMenuType parameter
to the show_window_menu () functions and use it to ask the compositor
to display the app menu when the new button is activated.

We want to synchronize the button layouts of our server side
decorations and GTK+'s client side ones. However each currently
may contain buttons not supported by the other, which makes this
unnecessarily tricky.
So add support for a new "appmenu" button in the layout, to display
the fallback app menu in the decorations.

It looks weird to have Alt+Space pop up under the cursor instead
of the top-left corner of the window, and the Wayland request will
pass through the coordinates as well.
Add it to the compositor interface, and extend the
_GTK_SHOW_WINDOW_MENU ClientMessage to support it as well.
We already do it in the theme code, but not the actual WM code. Since
we include the left/right borders, it only seems fair to include the
bottom border.
This effectively makes it so that shading a window means that the
client window "slot" has 0 height.
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.
