Since the recent clutter-content work, legacy scaling (in contrast
to the new stage-view-scaling) only applies to surfaces that belong
to a window. This broke scaling of DnD surfaces.
As a workaround, apply the same scaling on DnD-surface-actors until
we use stage-view-scaling by default and can remove this again.
Also: small corrections of geometry calculation
https://gitlab.gnome.org/GNOME/mutter/merge_requests/780
This allows us to implement more sophisticated logic for the different
cases. For DnD surfaces, use the geometry scale of the monitor where
the pointer is, instead of incorrectly assuming '1' as it was before.

The meta_display_update_focus_window() call has indirect dependencies
on the X11 focus window, in order to determine the correct focus window
on the Wayland side (i.e. may turn out NULL with certain X windows).
In order to have the right x11_display->focus_xwindow there, we should
perform first the focus update on the X11 display.
Fixes focusing of Java applications, as those don't seem to go through
_NET_ACTIVE_WINDOW.

With the addition of the locate-pointer special keybinding (defaults to
the [Control] key), we have now two separate special modifier keys which
can be triggered separately, one for the locate-pointer action and
another one for overlay.
When processing those special modifier keys, mutter must ensure that the
key was pressed alone, being a modifier, the key could otherwise be part
of another key combo.
As result, if both special modifiers keys are pressed simultaneously,
mutter will try to trigger the function for the second key being
pressed, and since those special modifier keys have no default handler
function set, that will crash mutter.
Check if the handler has a function associated and treat the keybinding
as not found if no handler function is set, as with the special modifier
keys.
https://gitlab.gnome.org/GNOME/mutter/issues/823
The `process_event()` would check for a existing keybinding handler and
abort if there is none, however the test is done after the handler had
been accessed, hence defeating the purpose of the check.
Move the check to verify there is an existing keybinding handler before
actually using it.

There were multiple bugs present after the ClutterContent transition.
Refactor `get_image` to:
- always assume surface coordinates for the clip
- return a cairo_surface in buffer size
- make the offscreen path take size arguments, so we can
easily change the assumption in get_image
- fix some clipping bugs on the way

Delayed clutter timelines might be removed while they are still in the
process of being executed, but if they are not playing yet their delay
timeout won't be stopped, causing them to be executed anyway, leading to a
potential crash.
In fact if something else keeps a reference on the timelines (i.e. gjs), the
dispose vfunc delay cancellation won't take effect, causing the timelines to
be started and added to the master clock.
To avoid this, expose clutter_timeline_cancel_delay() function and call it
if a timeline is not playing but has a delay set.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/815https://gitlab.gnome.org/GNOME/mutter/merge_requests/805
If a timeline is delayed and we request to stop or pause it, we are emitting
the "::paused" signal on it, however this has never been started, and so
nothing has really be paused.
So, just try to cancel the delay on pause and return if not playing.
No code in mutter or gnome-shell is affected by this, so it is safe to
change.

Some drivers expose EGL_EXT_image_dma_buf_import_modifiers so you can
query supported formats, but don't support any modifiers. Handle this by
treating it like DRM_FORMAT_MOD_INVALID.

Clutter stage used to compute the initial projection using a fixed z
translation which wasn't matching the one we computed in
calculate_z_translation().
This caused to have a wrong initial projection on startup which was then
correctly recomputed only at the first paint.
However, since this calculation doesn't depend on view, but only on viewport
size, perspective's fovy and z_near we can safely do this at startup and
only when any of those parameters change.
Then we can move the computation out _clutter_stage_maybe_setup_viewport()
since the cogl framebuffer viewport sizes aren't affecting this.

GCC's manpage says that this flag does the following:
Do not store floating-point variables in registers, and inhibit other
options that might change whether a floating-point value is taken from
a register or memory.
This option prevents undesirable excess precision on machines such as
the 68000 where the floating registers (of the 68881) keep more
precision than a "double" is supposed to have. Similarly for the x86
architecture. For most programs, the excess precision does only good,
but a few programs rely on the precise definition of IEEE floating
point.
We rely on this behaviour in our fork of clutter. When performing
floating point computations on x86, we are getting the wrong results
because of this architecture's use of the CPU's extended (x87, non-IEEE
confirming) precision by default. If we enable `-ffloat-store` here,
then we'll get the same results everywhere by storing into variables
instead of registers. This does not remove the need to be correct when
handling floats, but it does mean we don't need to be more correct than
the IEEE spec requires.

Instead of open coding the X11 focus management in display.c, expose
it as a single function with similar arguments to its MetaDisplay
counterpart. This just means less X11 specifics in display.c.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/751
MetaDisplay and MetaX11Display focus windows are slightly decoupled,
we cannot rely here on the MetaDisplay focus to be updated yet. We
however know the X Window that got focused, so lookup the corresponding
MetaWindow (and client X window) from it.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/751
We have a "setup" phase, used internally to initialize early the x11
side of things like the stack tracker, and an "opened" phase where
other upper parts may hook up to. This latter phase is delayed during
initialization so the upper parts have a change to connect to on
plugin creation.
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/771
When starting standalone mutter and running using the native backend, we
always fall back on using the us pc105 keyboard layout. This can be very
frustrating if one is used to using some other keyboard layout, such as
dvorak, causing keyboard fumbling everytime when doing something with
standalone mutter.
Avoid this involuntary fumbling by having the default plugin query
localed what layout the user has actually configured the machine to
operate using. It doesn't add any keymap selection user interface, so
it'll always use the first one it encounters.
