The GIR parser cannot figure out the ownership model of
ClutterStageView.get_framebuffer() and .get_offscreen()
without them, and throws us a couple of warnings.

Subject: [PATCH 03/49] clutter: Make ClutterStageView a public class
As a compositor toolkit, it makes sense to allow consumers
of Clutter interact with the stage views themselves. As such,
ClutterStageView should be a public class.
As such, it is now included in clutter.h and should not be
included directly.

Subject: [PATCH 05/49] clutter/stage: Emit after-paint after painting
ClutterStage:after-paint is supposed to be emitted after all
painting is done, but before the frame is finished. However,
as it is right now, it is being emitted after each view is
painted -- on multi-monitor setups, after-frame is being
emitted multiple times.
Send after-paint only once, after all views are painted and
before finishing the frame.

Subject: [PATCH 06/49] clutter/stage: Add ClutterStage:paint-view
Now that ClutterStageView is embraced as part of the public
set of Clutter classes, is it possible to give consumers
of this API more information and control over the drawing
routines of ClutterStage.
Introduce ClutterStage:paint-view, a signal that is emitted
for painting a specific view. It's defined as a RUN_LAST
signal to give anyone connecting to it the ability to run
before the view is actually painted, or after (using the
G_CONNECT_AFTER flag, or g_signal_connect_after).
This signal has a corresponding class handler, which allows
Mutter to have much finer control over the painting routines.
In fact, this will allow us to implement a "paint phase watcher"
mechanism in the following patches.

Subject: [PATCH 07/49] clutter/tests: Connect to ClutterStage:paint-view
ClutterStage:after-paint now does not guarantee a valid
implicit framebuffer pushed to the stack. Instead, use
the new 'paint-view' signal, that is emitted at a point
in the drawing routine where a framebuffer is pushed.
In addition to that, stop using the implicit framebuffer
API and port the actor-shader-effect test to read from
the view's framebuffer directly.

Subject: [PATCH 08/49] stage: Introduce MetaStageWatch and family
MetaStageWatch, watch modes and the watch function are part
of the new stage view watching API. It's design does not
rely on signals on purpose; the number of signals that would
be emitted would be too high, and would impact performance.
MetaStageWatch is an opaque structure outside of MetaStage.
This will be used by the screencast code to monitor a single
view, which has a one-to-one relatioship to logical monitors.

Subject: [PATCH 11/49] screen-cast/window: Use window actor damaged signal
instead of paint
We are really more interested in when a window is damaged, rather than
when it's painted, for screen casting windows. This also has the benefit
of not listening on the "paint" signal of the actor, meaning it'll open
doors for hacks currently necessary for taking a screenshot of a window
consisting of multiple surfaces.

Subject: [PATCH 12/49] window-actor: Add API to get a cairo surface of the
window
This currently uses a hack where it pushes a CoglFramebuffer backed by a
texture to the framebuffer stack, then calls clutter_actor_paint() on
the window actor causing it to render into the framebuffer. This has the
effect that all subsurfaces of a window will be drawn as part of the
window.

Subject: [PATCH 14/49] screen-cast: Fix window recording on HiDPI
Using the same scale for the window as the
logical monitor only works correctly when having
the experimental 'scale-monitor-framebuffer'
feature enabled.
Without this experimental feature, the stream
will contain a black screen, where the actual
window only takes a small part of it.
Therefore, use a scale of 1 for the non-
experimental case.
Patch is based on commit 3fa6a92cc5dda6ab3939c3e982185f6caf453360.

Subject: [PATCH 15/49] window-actor: Ensure clipping in `capture_into()`
The clip bounds passed in `meta_window_actor_capture_into()` represent
the actual allocated buffer size where the window actor image will be
eventually copied.
As such, it is completely agnostic to the scaling factors that might
affect the different surface actors which compose the window actor.
So instead of trying to compute the scale factor by which the given
clipping bounds need to be adjusted, simply clip the resulting image
based on the given bounds to make sure we never overflow the destination
buffer.

Subject: [PATCH 17/49] screen-cast-window: Use buffer bounds in place of frame
bounds
The frame bounds as returned by `meta_window_actor_get_frame_bounds()`
would be used as cropping values when streaming a window content.
But, as its name implies, it returns the actual frame bounds, whereas we
may want to include the whole buffer, to include client side shadows for
example.
Rename the `get_frame_bounds()` API to `get_buffer_bounds()` (which was
previously partly removed with commit 11bd84789) and return the actual
buffer bounds to use as the cropping area when streaming a window.
Fixes: 931934511 - "Implement MetaScreenCastWindow interface"
https://gitlab.gnome.org/GNOME/mutter/merge_requests/1022
Closes: https://gitlab.gnome.org/GNOME/mutter/issues/1018

Subject: [PATCH 19/49] egl: Introduce meta_egl_create_dmabuf_image
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 6f59e4858e24c828e3ab0e611d36dfaaded1b272 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.

Subject: [PATCH 23/49] dma-buf: Mark DMA-BUF textures as paint-only
Reading pixels directly from a texture imported from a DMA-BUF EGLImage
may result compressed textures to be transferred into non-compressed
texture. This may have side effects causing it to be rendered
incorrectly in subsequent paints.
Avoid this by passing the no-get-data flag to the texture creator
function, eventually causing mutter to use an intermediate offscreen
framebuffer when reading pixels from such textures.

Subject: [PATCH 24/49] cogl/framebuffer: Add cogl_framebuffer_flush
In future patches, we'll create additional CoglFramebuffers that
will be shared via DMA-Buf with PipeWire. When recording frames,
we'll blit the current onscreen framebuffer into the shared one.
However, that presents a problem: cogl_framebuffer_blit() mimics
glBlitFramebuffer() semantics, and doesn't do an implicit flush
of the GPU command stream. As a consequence, clients may receive
unblitted or incomplete framebuffers.
We could use cogl_framebuffer_finish() to ensure the commands were
submitted to the GPU, but it is too harsh -- it blocks the CPU
completely until the commands are finished!
Add cogl_framebuffer_flush(), which ensures the command stream is
submitted to the GPU without blocking the CPU. Even though we don't
use the framebuffer specifically, it may be useful in the future
for e.g. a potential Vulkan backend to have access to the framebuffer.

Subject: [PATCH 25/49] cogl/context: Add cogl_renderer_create_dma_buf() and
family
This is a winsys-specific API that allows exporting a DMA buffer fd.
The CoglDmaBufHandle structure allows passing the ownership of the
DMA buffer to whoever is using it, so the winsys doesn't need to
manually track it.

Subject: [PATCH 27/49] renderer-native: Implement DMA buffer creation
Create a new gbm_bo using the same given geometry, and export the new
bo's DMA buffer fd. The new bo lives as long as necessary to be used,
and reused, by PipeWire.
Unfortunately, PipeWire doesn't support modifiers properly, so use the
linear format for now. For now, a hardcoded format of DRM_FORMAT_XRGB8888
is set, so we don't need to negotiate the format with PipeWire early.

Subject: [PATCH 28/49] screen-cast-stream-src: Support DMA buffer sharing
Implement PipeWire's add_buffer and remove buffer, try and export
a DMA buffer first and, on failure, fallback to memfd.
When DMA buffers are successfully created and shared, blit the
framebuffer contents when drawing instead of downloading the pixels.

Subject: [PATCH 30/49] window-stream-source: Draw into DMA buffer image
Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context
that used the passed framebuffer.
Now that all MetaScreenCastStreamSrc subclasses implement
blit_to_framebuffer, remove the conditional check from
meta_screen_cast_stream_src_blit_to_framebuffer().

Subject: [PATCH 32/49] monitor-stream-src: Use cogl_framebuffer_finish()
Even though cogl_framebuffer_flush() was supposed to be enough,
it ends up creating streams with odd visual glitches that look
very much like unfinished frames.
Switch back to cogl_framebuffer_finish(), which is admittedly
an overkill, but it's what works for now. There is anedoctal
evidence showing it doesn't incur in worse performance.

Subject: [PATCH 34/49] screen-cast-stream-src: Don't leak GSource
For every stream src, we created and attached a GSource. Upon stream
src destruction, we g_source_destroy():ed the GSource. What
g_source_destroy() does, hawever, is not really "destroy" it but only
detaches it from the main context removing the reference the context had
added for it via g_source_attach(). This caused the GSource to leak,
although in a detached state, as the reference taken on creation was
still held.
Fix this by also removing our own reference to it when finalizing.

Subject: [PATCH 36/49] window-actor: Clip before translate when blitting
cogl_framebuffer_push_rectangle_clip() acts on the current modelview
matrix. That means the result of clipping then translating will be
different of the result of translating then clipping.
What we want for window screencasting is the former, not the latter.
Move the translation code (and associated) to after clipping.

Subject: [PATCH 37/49] window-stream-src: Ensure initial frame is recorded
MetaScreenCastWindowStreamSrc connects to the "damaged" signal of
MetaWindowActor. This signal is not exactly tied to the paint cycle
of the stage, and a damage may take quite a while to arrive when
a client doesn't want to draw anything. For that reason, the window
screencast can start empty, waiting for a damage to arrive.
Ensure at least one frame is recorded when enabling the window stream.

Subject: [PATCH 41/49] window-actor: Inhibit culling when blitting to
screencast
This allows us to screencast any window continuously, even
without it being visible. Because it's still being painted,
clients continue to receive frame callbacks, and people
are happy again.

Subject: [PATCH 44/49] screen-cast-src: Notify that about the stream being
closed on idle
We're iterating inside the PipeWire loop when detecting PipeWire errors,
and shouldn't destroy the PipeWire objects mid-iteration. Avoid this by
first disabling the stream src (effectively stopping the recording),
then notifying about it being closed in an idle callback. The
notification eventually makes the rest of the screen cast code clean up
the objects, including the src and the associated PipeWire objects, but
will do so outside the PipeWire loop iteration.

Subject: [PATCH 48/49] backends: Make uniform checks on remote desktop input
dbus methods
They all checked that the remote session service talked with the
correct peer, and some of them did check that there is an associated
screencast session.
Add a new check for the session being started (as it's state is
decoupled with screencast session availability) and move all checks
to a function that is called from all input-oriented DBus methods.

Subject: [PATCH 49/49] remote-access-controller: Allow inhibiting remote
access
Inhibiting remote access means any current remote access session is
terminated, and no new ones can be created, until remote access is
uninhibited. The inhibitation is ref counted, meaning there can be more
than one inhibitor.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1212
(cherry picked from commit 4300f1f91d726051893146d7b294d8852782f137)
