test_client_new might return early if conditions are not met, leaving some
allocated data around without freeing it.
Since we're not using the client before, there's no need to initialize it early
and just initialize it when it's going to be returned.

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.
Fix this by adding those targets when they are missing and the selection
source provides the corresponding mimetypes.

(cherry picked from commit c7d14244b1)
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.

(cherry picked from commit e1c4e55880)
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%.

(cherry picked from commit 32dbcd9352)
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.

It doesn't take all children - subsurfaces in this case - into
account, thus creating glitches if subsurfaces extend outside
of the toplevel surface.
Further more it doesn't seem to serve any special purpose - it was
added in f7315c9a36, a pretty big commit, and no discussion was
started about the code in question. So it was likely just overlooked
in the review process.

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.

Now that we don't use the record function to early out depending on
implicit state (don't record pixels if only cursor moved for example),
let it simply report an error when it fails, as we should no longer ever
return without pixels if nothing failed.

Both do more or less the same but with different methods - one puts
pixels into a buffer using the CPU, the other puts pixels into a buffer
using the GPU.
However, they are behaving slightly different, which they shouldn't.
Lets first address the misleading disconnect in naming, and later we'll
make them behave more similarly.

ClutterBoxLayout calculates the preferred size of the opposite
orientation (so for example the height if the orientation is horizontal)
by getting the preferred size of the real orientation first, and then
the preferred size of the opposite orientation, using the other size as
for_width/height when doing the request.
Right now, for non-homogeneous layouts this for_width/height does not
adjust for the spacing set on the box layout. This leads to children
being passed a slightly larger for_width/height, which in case of
ClutterText might cause the line to not wrap when it actually should.
This in turn means we can end up with an incorrect preferred size for
the opposite orientation, leading to a wrong allocation.
So fix that and adjust for the spacing just as we do for homogeneous
layouts by subtracting the total spacing from the available size that is
distributed between children.
This fixes the wrong height of the checkbox label reported in
https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2574.

41130b08eb added a fix for culling subsurfaces with geometry scale.
Unfortunately it only did so for the opaque regions, not for clip and
unobscured regions, as the effect was hidden by bug that was only
fixed by 3187fe8ebc.
Apply the same fix to clip and unobscured regions and use the chance
to move most of the slightly hackish geometry scale related code
into a single place.
We need to scale slightly differently in the two cases, indicated by
the new `ScalePerspectiveType` enum, as the scale is dependent on the
perspective - once from outside, once from inside of the scaled actor.

The portal API requires a screencast session only for absolution motion
with remote desktop, other methods including relative motion do not
require a screencast session.
There is no reason to be more strict than the API actually is, check for
a screencast session only when required, like for absolute motion events
and touch events.

(cherry picked from commit b8524504f4)
We were setting the pipeline colour to all white (1.0, 1.0, 1.0, 1.0)
and so the default layer combine function multiplied each pixel
(R, G, B, A) by all ones. Obviously multiplying by one four times per
pixel is a waste of effort so we remove the colour setting *and* set
the layer combine function to a trivial shader that will ignore whatever
the current pipeline colour is set to. So now we do **zero** multiplies
per pixel.
On an i7-7700 at UHD 3840x2160 this results in 5% faster render times
and 10% lower power usage (says intel_gpu_top). The benefit is probably
much higher for virtual machines though, as they're no longer being
asked to do CPU-based math on every pixel of a window.

When an app disappears after some data from it has been copied to the
clipboard, the owner of the clipboard selection becomes a new memory
selection source. The initial reference this new selection source is
never unref'ed, which leads to this being leaked on the next clipboard
selection owner change.

Instead of having everything clumped at MetaWaylandDataManager,
split the primary selection to its own struct. This manager is
handled separately from wl_data_device_manager and other selection
managers, so they would be able to interoperate between them, even.

This is still an openly defined struct, as we will need accessed
by "subclasses". Same principle applies than with the
MetaWaylandDataSource refactor, this is not meant to introduce
functional changes, so just go with it.
On the bright side, the interactions are now clearer, so it could
be made saner in the future.

The split wasn't 100% clean, and some extra private API had to be

there's a cleanup/streamlining task due). This is meant to be a

meta-native-renderer.c:dummy_power_save_page_flip →
meta_onscreen_native_swap_drm_fb implicitly turning of the primary
plane (by destroying the KMS framebuffer assigned to it):

between setting a non-empty cursor with drmModeSetCursor(2) and
enabling the primary plane again:
Failed to DPMS: Failed to set connector 69 property 2: Invalid argument
(This was harmless other than the error message, as we always re-set
a mode on the CRTC after setting the DPMS property to on, which
enables the primary plane and implicitly sets the DRM property to on)

In commit 4c1fde9d MetaCullable related code was moved out of
MetaShapedTexture into MetaSurfaceActor. While generally desirable,
this removed drawing optimizations in MetaShapedTexture for partial
redraws. The common case for fully obscured actors was still supposed
to work, but it was now discovered that it actually did not.
This commit revert parts of 4c1fde9d: it reintroduces clipping
to MetaShapedTexture but leaves all culling and actor related logic
in MetaSurfaceActor.
Thanks to Daniel van Vugt for uncovering the issue.

The size of the buffer the texture will be written to by
paint_to_buffer() is determined based on
meta_screen_cast_area_stream_src_get_specs() which uses roundf() to
calculate the width and height after scaling. Because the size of the
texture to be written to that buffer is calculated using ceilf(), it
might exceed the allocated buffer when using fractional scaling.
In 3.36 paint_to_buffer() is used from capture_view() which also uses
roundf() to allocate its buffer. Here this leads to a memory corruption
resulting in a crash when taking screenshots of an area.
