We want to clip it away if 1) The window is fully opaque or
2) If it's translucent but has a frame (as explained in the comment
above). The code didn't quite match and we were only applying it on
case #2.
Case #1 is far more common, and saves us from pushing some drawing
that we know will be covered in the end.

`g_object_notify()` actually takes a global lock to look up the property
by its name, which means there is a performance hit (albeit tiny) every
time this function is called. For this reason, always try to use
`g_object_notify_by_pspec()` instead.

We first set the workspace to the transient-for parent's, and then
try to set on the current workspace. If both happen, we double the
work on adding/removing it from the workspace, and everything that
happens in result.
Should reduce some activity while typing on the Epiphany address
bar, as the animation results in a number of xdg_popup being created
and destroyed to handle the animation.

Since the API version was added, we've bumped it at some point late-ish in
the cycle when enough changes had accumulated (but way after the first ABI
break). Automate that process by computing the API version automatically
from the project version:
With this commit, the new API version will be 5 for the remaining 3.33.x
releases and all 3.34.x stable versions; 3.35.1 will then bump it to 6 and
so forth.

Since commit 0eab73dc, actors are only allocated when they are actually
visible. While this generally works well, it breaks - because of *course*
it does - ClutterClones when the clone source (or any of its ancestors)
is hidden.
Force an allocation in that case to allow the clone's paint to work as
intended.

The default configuration of libinput-gestures utility invokes wmctrl to
switch between desktops. It uses wmctrl because this works on both Xorg
and Wayland (via XWayland). Unfortunately, this generates the following
warning message every time, in both Xorg and Wayland desktops:
"Received a NET_CURRENT_DESKTOP message from a broken (outdated) client
who sent a 0 timestamp"
The desktop switch still works fine. The tiny code change here removes
this specific warning because, as the prefacing code comment originally
said and still says, older clients can validly pass a 0 time value so
why complain about that?
I also refactored the "if (workspace)" code slightly to avoid the double
test of the workspace value.
This is submitted for MR
https://gitlab.gnome.org/GNOME/mutter/merge_requests/671.
On X11, mutter needs to keep a grab on the locate-pointer key to be able
to trigger the functionality time the corresponding key combo is
pressed.
However, doing so may have side effects on other X11 clients that would
want to have a grab on the same key.
Make sure we only actually grab the key combo for "locate-pointer" only
when the feature is actually enabled, so that having the locate pointer
feature turned off (the default) would not cause side effects on other
X11 clients that might want to use the same key for their own use.
Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/647
Some special modifiers (typically "Control_L" used for locate-pointer in
mutter/gnome-shell or "Super_L" for overlay) must be handled separately
from the rest of the key bindings.
Add a new flag `META_KEY_BINDING_NO_AUTO_GRAB` so we can tell when
dealing with that special keybinding which should not be grabbed
automatically like the rest of the keybindings, and skip those when
changing the grabs of all keybindings.

The type has been deprecated, so stop using it. The easiest replacement
would be to add our own struct, but considering that separate name/value
arrays are easier to free (g_auto!) and we already do the split in one
place, go that route.

Glib stopped providing any fallback implementations on systems without
memmove() all the way back in 2013. Since then, the symbol is a simple
macro around memmove(); use that function directly now that glib added
a deprecation warning.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/689
Starting with commit 2db94e2e we try to focus a fallback default focus window
if no take-focus window candidate gets the input focus when we request it and
we limit the focus candidates to the current window's workspace.
However, if the window is unmanaging, the workspace might be unset, and we could
end up in deferencing a NULL pointer causing a crash.
So, in case the window's workspace is unset, just use the currently active
workspace for the display.

Make it so it returns the closest ancestry MetaWindowActor if it
is a MetaSurfaceActor.
We need this for Wayland subsurfaces, so we can support actions like
Meta+Drag on them.

Saves us from using MetaCompositor API, at a point where it might not
be initialized yet. Use the same window directly, since we already
have it handy.

This is important when using a touchscreen or stylus instead of a mouse
or touchpad. If the cursor only gets hidden and the focus stays the
same, the window will still send hover events to the UI element under
the cursor causing unexpected distractions while interacting with the
touchscreen.
Fix this by emitting a visibility-changed signal from the cursor tracker
which then triggers a focus surface sync and always set the focus
surface to NULL when it's synced while the cursor is hidden.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/448
Allow checking whether the pointer is visible without accessing the
trackers internal is_showing property. While we don't need this just yet
for reading the visibility inside meta-wayland-pointer, it's useful when
implementing the logic to remove Clutter's focus when the cursor goes
hidden later.

COPY_MODE_PRIMARY has two paths, automatically chosen. For debugging purposes,
e.g. why is my DisplayLink screen slowing down the whole desktop, it will be
useful to know which copy path is taken. Debug prints are added to both when
the primary GPU copy succeeds the first time and when it fails the first time.
This is not the full truth, because theoretically the success/failure could
change every frame, but we don't want to spam the logs (even in debug mode)
every frame. In practise, it should be rare for the success or failure to ever
change. Hence, saying what happened on the first time is enough. This does
indicate if it ever changes even once, too, so we know if that unexpected thing
happens.
The debug prints are per secondary GPU since there could be several.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
When the preferred path META_SHARED_FRAMEBUFFER_COPY_MODE_SECONDARY_GPU cannot
be used, as is the case for e.g. DisplayLink devices which do not actually have
a GPU, try to use the primary GPU for the copying before falling back to
read-pixels which is a CPU copy.
When the primary GPU copy works, it should be a significant performance win
over the CPU copy by avoiding stalling libmutter for the duration.
This also renames META_SHARED_FRAMEBUFFER_COPY_MODE_* because the new names are
more accurate. While the secondary GPU copy is always a GPU copy, the primary
copy might be either a CPU or a GPU copy.

This bit of code was more or less duplicated in meta-renderer-native-gles3.c
and meta-wayland-dma-buf.c. Start consolidating the two implementations by
moving the *-gles3.c function into meta-egl.c and generalizing it so it could
also accommodate the meta-wayland-dma-buf.c usage.
The workaround in the *-gles3.c implementation is moved to the caller. It is
the caller's responsibility to check for the existence of the appropriate EGL
extensions.
Commit 6f59e4858e worked around the lack of
EGL_EXT_image_dma_buf_import_modifiers with the assumption that if the modifier
is linear, there is no need to pass it into EGL. The problem is that not
passing a modifier explicitly to EGL invokes implementation-defined behaviour,
so we should not have that workaround in meta-egl.c.
This patch intends to be pure refactoring, no behavioral changes. The one
change is the addition of g_assert to catch overwriting arbitrary memory.

The function will be used in copying from a primary GPU framebuffer to a
secondary GPU framebuffer using the primary GPU specifically when the
secondary GPU is not render-capable.
To allow falling back in case glBlitFramebuffer cannot be used, add boolean
return value, and GError argument for debugging purposes.

Depends on "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
Allow blitting between onscreen and offscreen framebuffers by doing the y-flip
as necessary. This was not possible with ANGLE, but now with ANGLE gone,
glBlitFramebuffer supports flipping the copied image.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
Depends on: "cogl: Replace ANGLE with GLES3 and NV framebuffer_blit"
As a possible ANGLE implementation is not longer limiting the pixel format
matching, lift the requirement of having the same pixel format.
We still cannot do a premult <-> non-premult conversion during a blit, so guard
against that.
This will be useful in follow-up work to copy from onscreen primary GPU
framebuffer to an offscreen secondary GPU framebuffer if the formats do not
match exactly.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/615
ANGLE extensions are only provided by Google's Almost Native Graphics Layer
Engine (ANGLE) implementation. Therefore they do not seem too useful for
Mutter.
The reason to drop GL_ANGLE_framebuffer_blit support is that it has more
limitations compared to the glBlitFramebuffer in GL_EXT_framebuffer_blit,
GL_NV_framebuffer_bit, OpenGL 3.0 and OpenGL ES 3.0. Most importantly, the
ANGLE version cannot flip the image while copying, which limits
_cogl_blit_framebuffer to only off-screen <-> off-screen copies. Follow-up work
will need off-screen <-> on-screen copies.
Instead of adding yet more capability flags to Cogl, dropping ANGLE support
seems appropriate.
The NV extension is added to the list of glBlitFramebuffer providers because it
provides the same support as ANGLE and more.
Likewise OpenGL ES 3.0 is added to the list of glBlitFramebuffer providers
because e.g. Mesa GLES implementation usually provides it and that makes it
widely available, again surpassing the ANGLE supported features.
Follow-up patches will lift some of the Cogl assumptions of what
glBlitFramebuffer cannot do.
