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.
Rather than calculate it speculatively with the current properties
which may be too new or too out of date, make sure it always fits
with the proper definition. We update it when we update the toplevel
window for X11, and when a Wayland surface is committed with a newly
attached buffer.
With get_input_region existing, get_input_rect is a misnomer. Really,
it's about the geometry of the output surface, and it's only used that
way in the compositor code.
Way back when in GNOME 3.2, get_input_rect was added when we added
invisible borders. get_outer_rect was always synonymous with server-side
geometry of the toplevel. get_outer_rect was used for both user-side
policy (the "frame rect") and to get the geometry of the window.
Invisible borders were meant to extend the input region of the frame
window silently. Since most users of get_outer_rect cared about the
frame rect, we kept that the same and added a new method, get_input_rect
to get the full rect of the framed window with all invisible borders for
input kept on.
As time went on and CSD and Wayland became a reality, the relationship
between the server-side geometry and the "frame rect" became more
complicated, as can be evidenced by the recent commits. Since clients
don't tend to be framed anymore, they set their own input region.
get_buffer_rect is also sort of a poor name, since X11 doesn't really
have buffers, but we don't really have many other alternatives.
This doesn't change any of the code, nor the meaning. It will always
refer to the rectangle where the toplevel should be placed.
All of the users of get_input_rect don't actually want a synthesized
input rect based off of the current margins. What they really want is
the last-configured size of the toplevel window.
Since we don't properly track this anymore in the generic MetaWindow,
use XGetWindowAttributes to fetch a server-side rectangle. This is a
bad layer violation, but since the window geometry code will have to
be rewritten anyway for the Wayland set_window_geometry, let's just
push a hacky fix for now.
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.

Struts are defined in terms of screen edges, so expand the rectangles
we get via set_builtin_struts() accordingly. However we do want to
allow chrome on edges between monitors, in which case the expansion
would render an entire monitor unusable - don't expand the rectangles
in that case, which means we will only use them for constraining
windows but ignore them for the client-visible _NET_WORKAREA property.
https://bugzilla.gnome.org/show_bug.cgi?id=730527
Like the _NET_WM_STRUT/_NET_WM_STRUT_PARTIAL client properties,
_NET_WORKAREA is defined in terms of screen geometry rather than
taking individual monitors into account. However we do want to
allow system chrome to be attached to a monitor edge rather than
a screen edges under some circumstances. As not all clients can
be assumed to deal gracefully with the resulting workarea, use
those "struts" only internally for constraining windows, but
ignore them when exporting _NET_WORKAREA.

Since commit 8b2b65246a, we assume that the compositor always
exists. Alas, the assumption is wrong - the compositor is currently
initialized after the screen, but meta_screen_new() itself may
call a compositor function if initialization involves a workspace
switch (which will happen when meta_workspace_activate() is called
more than once and for different workspaces - or in other words,
when _NET_CURRENT_DESKTOP is set and not 0).
So carefully split out the offending bits and only call them after
the compositor has been initialized.

If we have a tree of a window, a non-attached dialog, and then an
attached dialog, we want to move the second window, not the attached
dialog or the topmost. In other words, we want to move the first
non-attached window, or the first "freefloating window".
This happens in Firefox, whose Preferences dialog is freefloating,
but suboptions of those are modal dialogs.
There is no way this value will ever be read, because we set the
cursor_surface to NULL, this is set at the same time as cursor_surface,
and it's only read if cursor_surface is non-NULL.
The smallest possible spread corresponds to an unblurred shadow, which
neither grows nor shrinks - thus the spread should be zero not negative
as returned by our current calculation.

Stupid apps fullscreen themselves by resizing the client window to
monitor size. A monitor-sized frame rect on the other hand is perfectly
normal on monitors without struts - stop force-fullscreening those
and catch the real baddies instead.

Avoid populating *_VERSION constants through cflags in pkg-config-file
which could be overridden by the project using it. Properly prefix the
defines with META_ to make gi-scanner happy.
Clutter touch events are translated into events being sent down
the interface resource, with the exception of FRAME/CANCEL events,
which are handled directly via an evdev event filter.
The seat now announces invariably the WL_SEAT_CAPABILITY_TOUCH
capability, this should be eventually updated as devices come and
go.
The creation of MetaWaylandTouchSurface structs is dynamic, attached
to the lifetime of first/last touch on the client surface, and only
if the surface requests the wl_touch interface. MetaWaylandTouchInfo
structs are created to track individual touches, and are locked to
a single MetaWaylandTouchSurface (the implicit grab surface) determined
on CLUTTER_TOUCH_BEGIN.

There's a race here. If an OR window hides itself, moves, and then shows
itself, we will send a ConfigureNotify for the old size of the window
and might receive it after the client moves itself, causing us to show
the window at the wrong location.
Simply not sending the ConfigureNotify is the easiest thing to do.
Before we unmanage, we send a ConfigureNotify to clients to let them
know if their frame is destroyed. We do this for OR windows too, even if
we really probably shouldn't.
This is based off of the client_rect. Since we listen to ConfigureNotify
on OR windows, we'll receive the event. If we don't ever update the
client_rect when moving or resizing OR windows, then we'll send
ourselves a ConfigureNotify for a 0x0 size and then think that the
client chose a new size for itself. Since our get_paint_volume is based
on that rectangle, but the TFP code inside Cogl uses XGetGeometry
itself, we get weird flickering artifacts.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=731058
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.
https://bugzilla.gnome.org/show_bug.cgi?id=731058
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.
https://bugzilla.gnome.org/show_bug.cgi?id=731058
This can happen since we select for events on the root window, and
clients themselves might not select for input, meaning the X server
will bubble up. Just do nothing and ignore the event in this case.
This should hopefully fix some of the
Window manager warning: Log level 8: meta_window_raise: assertion '!window->override_redirect' failed
Window manager warning: Log level 8: meta_window_focus: assertion '!window->override_redirect' failed
spam that people have been seeing.
Smooth scroll event vectors from clutter have the same dimensions as the
ones from from Xi2, i.e. where 1.0 is 1 discrete scroll step. To scale
these to the coordinate space used by wl_pointer.axis
vertical/horizontal scroll events, multiply the vector by 10.

Since we often call meta_window_move_resize_now immediately after
mapping a window, we need to make sure that the placed coordinates
are saved in the unconstrained_rect. Ideally, placement positions
wouldn't be part of the constraints system, but instead are just
done inside meta_window_move_resize_internal as part of a special
path.
We're still working out the kinks of one large-scale refactor, so
it's best not to do another one while the first is going on. This
would be a great future cleanup, though: untangling constraints
and placement, alongside the force_placement state machine and
friends.
For Wayland, we want to have everything possible in terms of the frame
rect, or "window geometry" as the Wayland protocol calls it, in order
to properly eliminate some flashing when changing states to fullscreen
or similar.
For this, we need to heavily refactor how the code is structured, and
make it so that meta_window_move_resize_internal is specified in terms
of the frame rect coordinate space, and transforming all entry points
to meta_window_move_resize_internal.
This is a big commit that's hard to tear apart. I tried to split it
as best I can, but there's still just a large amount of changes that
need to happen at once.
Expect some regressions from this. Sorry for any temporary regression
that this might cause.
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, ...)
Now that meta_window_move_resize and friends act in frame rect
coordinates, we need to convert the initial grab_anchor_window_pos
storage to be in frame rect coordinates as well.
This makes Alt+F7 / Alt+F8 work respectively under X11 nested mode.
For the native backend implementation, we'll need a special Clutter
function, so don't implement that for now.
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.
https://bugzilla.gnome.org/show_bug.cgi?id=730752
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.
https://bugzilla.gnome.org/show_bug.cgi?id=730752
meta_window_get_position() returns the client rect position, which
we then pass to meta_window_move_frame. Just use the existing frame
rect coordinates.
The requested_rect is a strange name for it, because it's not actually
the rect that the user or client requested all the time: in the case of
a simple move or a simple resize, we calculate some of the fields
ourselves.
To the MetaWindow subclass implementations, it just means "the rect
before we constrained it", so just use the name unconstrained_rect.
This also makes it match the name of the MetaWindow field.
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.
On X, basing the check whether the pointer is on the window on
Clutter events does not work, as the relevant events are handled
by GDK instead.
So add an X-specific window_has_pointer() implementation to also
fix mouse mode when running as X compositor.
https://bugzilla.gnome.org/show_bug.cgi?id=730541
Using clutter_actor_has_pointer() to test whether the pointer is
on the window makes for clean and nice-looking code, but does not
work in practice - ClutterActor:has-pointer is not recursive, so
we miss when the pointer is on the associated surface actor rather
than the actor itself.
Instead, check whether the window actor contains the core pointer's
pointer actor, which actually works.
https://bugzilla.gnome.org/show_bug.cgi?id=730541
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.
