fcf7c4d0c7 cursor-renderer: Always keep the cursor overlay on the stage
Only when the cursor isn't handled by the backend is the overlay made
visible. This is intended to be used when painting the stage to an
offscreen using clutter_stage_paint_to_(frame)buffer() in a way where
the cursor is always included.

f894f5cc13 wayland: Add API to launch trusted clients
Allowing code from inside mutter to create a child process and
delegate on it some of its tasks is something very useful. This can
be done easily with the g_subprocess and g_subprocess_launcher classes
already available in GLib and GObject.

Unfortunately, although the child process can be a graphical program,
currently it is not possible for the inner code to identify the
windows created by the child in a secure manner (this is: being able
to ensure that a malicious program won't be able to trick the inner
code into thinking it is a child process launched by it).

Under X11 this is not a problem because any program has full control
over their windows, but under Wayland it is a different story: a
program can't neither force their window to be kept at the top (like a
docker program does) or at the bottom (like a program for desktop icons
does), nor hide it from the list of windows. This means that it is not
possible for a "classic", non-priviledged program, to fulfill these
tasks, and it can be done only from code inside mutter (like a
gnome-shell extension).

This is a non desirable situation, because an extension runs in the
same main loop than the whole desktop itself, which means that a
complex extension can need to do too much work inside the main loop,
and freeze the whole desktop for too much time. Also, it is important
to note that javascript doesn't have access to fork(), or threads,
which means that, at most, all the parallel computing that can do is
those available in the _async calls in GLib/GObject.

Also, having to create an extension for any priviledged graphical
element is an stopper for a lot of programmers who already know
GTK+ but doesn't know Clutter.

This patch wants to offer a solution to this problem, by offering a
new class that allows to launch a trusted child process from inside
mutter, and make it to use an specific UNIX socket to communicate
with the compositor. It also allows to check whether an specific
MetaWindow was created by one of this trusted child processes or not.

This allows to create extensions that launch a child process, and
when that process creates a window, the extension can confirm in a
secure way that the window really belongs to that process
launched by it, so it can give to that window "superpowers" like
being kept at the bottom of the desktop, not being listed in the
list of windows or shown in the Activities panel... Also, in future
versions, it could easily implement protocol extensions that only
could be used by these trusted child processes.

Several examples of the usefulness of this are that, with it, it
is possible to write programs that implements:

- desktop icons
- a dock
- a top or bottom bar
...

all in a secure manner, avoiding insecure programs to do the same.
In fact, even if the same code is launched manually, it won't have
those privileges, only the specific process launched from inside
mutter.

Since this is only needed under Wayland, it won't work under X11.

109fbdbac9 clutter/actor: Add get_transformed_extents
The clutter_actor_get_transformed_position returns the position of the
top left point of the actor, with the actor transformations. That means
that if the actor is rotated 180º it'll return the "screen" position top
right.

Using this to calculate if the actor is in the screen is causing
problems when it's transformted.

This patch adds a new function clutter_actor_get_transformed_extents,
that will return the transformed actor bounding rect.

This new function is used on the update_stage_views so the actor will
get updated. this way rotated actors will be updated if they are on the
screen.

ca64a308eb surface-actor: Restore drop shadow with server-side decorations
Commit 510cbef15a changed the logic in `handle_update()` for X11 window
actors to return early if the surface is not an X11 surface.

That works fine for plain Xorg, but on Xwayland, the surface is actually
a Wayland surface, therefore the function returns early before updating
the drop shadows of server-side decorations for X11 windows.

Change the test logic to restore drops shadows with Xwayland windows.

c7d14244b1 x11: Add STRING/UTF8_STRING targets for selection sources lacking them
The memory selection source was only providing the "text/plain" or the
"text/plain;charset=utf-8" mimetype, but not "STRING" or "UTF8_STRING",
which some X11 clients, like wine, are looking for. This was breaking
pasting from the clipboard in wine applications.

e1c4e55880 x11: Handle selection windows being destroyed before new selection
Wine destroys its old selection window immediately before creating a new
selection. This would trigger restoring the clipboard, which would
overwrite the new selection with the old one. The selection window
however can also be destroyed as part of the shutdown process of
applications, such as Chromium for example. In those cases we want the
clipboard to be restored after the selection window has been destroyed.

Solve this by not immediately restoring the clipboard but instead using
a timeout which can be canceled by any new selection owner, such as in
the Wine case.

0aa4bab539 kms: Use custom page flip function when retrying failed flips
When using its EGLStream-based presentation path with the proprietary NVIDIA
driver, mutter will use a different function to process page flips -
custom_egl_stream_page_flip.  If that fails due to an EBUSY error, it will
attempt to retry the flip.  However, when retrying, it unconditionally uses the
libdrm-based path. In practice, this causes a segfault when attempting to
access plane_assignments->fb_id, since plane_assignments will be NULL in the
EGLStream case.  The issue can be reproduced reliably by VT-switching away from
GNOME and back again while an EGL application is running.

This patch has mutter also use the custom page flip function when retrying the
failed flip.

Because `gsettings-desktop-schemas.pc` says:

Which means to include the version that Meson has configured you need
to drop the directory prefix and only `#include <gdesktop-enums.h>`.

9bab8e8751 screen-cast/src: Record follow up frame after timeout
During animation or other things that cause multiple frames in a row
being painted, we might skip recording frames if the max framerate is
reached.

Doing so means we might end up skipping the last frame in a series,
ending with the last frame we sent was not the last one, making things
appear to get stuck sometimes.

Handle this by creating a timeout if we ever throttle, and at the time
the timeout callback is triggered, make sure we eventually send an up to
date frame.

This is handle differently depending on the source type. A monitor
source type reports 1x1 pixel damage on each view its monitor overlaps,
while a window source type simply records a frame from the surface
directly, except without recording a timestamp, so that timestamps
always refer to when damage actually happened.

ecaaccb064 background: Use NEAREST filtering when the texture is the monitor resolution
That was obviously always the intention, but it didn't work when the
display was scaled. My 3840x2160 monitor with a 3840x2160 texture was
being rendered with LINEAR filtering.

It seems the `force_bilinear` flag was TRUE when it should be FALSE.
Because a texture area that's an integer fraction of the texture
resolution is still a perfect match when that integer is the monitor
scale. We were also getting:

`meta_actor_painting_untransformed (fb, W, H, W, H, NULL, NULL) == FALSE`

when the display was scaled. Because the second W,H was not the real
sampling resolution. So with both of those issues fixed we now get
NEAREST filtering when the texture resolution matches the resolution it's
physically being rendered at.

Note: The background texture actually wasn't equal to the physical monitor
resolution prior to January 2020 (76240e24f7). So it wasn't possible to do
this before then. Since then however, the texture resolution is always
equal to the physical monitor resolution.

03d177cf64 clutter/actor: Add position argument to allocate_preferred_size()
Make clutter_actor_allocate_preferred_size() convenient to use from
layout managers by not "automatically" honouring the fixed position of
the actor, but instead allowing to pass a position to allocate the
actor at.

This way we can move the handling of fixed positions to
ClutterFixedLayout, the layout manager which is responsible for
allocating actors using fixed positions.

This also makes clutter_actor_allocate_preferred_size() more similar to
clutter_actor_allocate_available_size().

dfa235aa5d clutter/actor: Add API to get fixed position
It's currently a bit hard to get the fixed position of an actor. It can
be either done by using g_object_get() with the "fixed-x"/"fixed-y"
properties or by calling clutter_actor_get_position().

Calling clutter_actor_get_position() can return the fixed position, but
it might also return the allocated position if the allocation is valid.
The latter is not the best behavior when querying the fixed position
during an allocation, so introduce a new function
clutter_actor_get_fixed_position() which always gets the fixed position
and returns FALSE in case no fixed position is set.

32dbcd9352 background-content: Mipmap background texture rendering
gnome-shell displays workspace previews at one tenth scale. That's a
few binary orders of magnitude so even using a LINEAR filter was
resulting in visible jaggies. Now we apply mipmapping so they appear
smooth.

As an added bonus, the mipmaps used occupy roughly 1% the memory of
the original image (0.1 x 0.1 = 0.01) so they actually fit into GPU/CPU
caches now and rendering performance is improved. There's no need to
traverse the original texture which at 4K resolution occupies 33MB,
only a 331KB mipmap.

In my case this reduces the render time for the overview by ~10%.

3a474556b8 cogl-texture-2d: Flush the journal before mipmapping
In the case of indirect rendering like the first frame to use mutter's
background wallpaper:

  Texture_A -> FBO_B (Texture_B) -> FBO_C (screen)

we would be trying to render the contents of both FBO_B and FBO_C in
the same flush, before the contents of Texture_A had made it to FBO_B.
So when FBO_C wants to use mipmaps of Texture_B they didn't exist yet
and appeared all black. And the blackness would remain for subsequent
frames as cogl has now decided the mipmaps of FBO_B are no longer
"dirty" and don't need refreshing:

  FBO_B (Texture_B) (mipmaps_dirty==FALSE but black) -> FBO_C (screen)

We must flush FBO_B before referencing Texture_B for use in rendering
FBO_C. This only happens when Texture_A changes (e.g. when the user
changes their background wallpaper) so there's no ongoing performance
penalty from this flush.
