The ClutterRootNode paint node is theoretically the
top-most node of a paint nodes tree, except that we
are not in the point of having full rendering trees
in Clutter (all rendering performed by paint nodes
is still local and immediate).
When controlling the rendering tree, MetaShapedTexture
may need to paint into an offscreen framebuffer under
some circumstations.
Expose ClutterRootNode so that MetaShapedTexture can
use it to render to offscreen framebuffers.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
When painting to an offscreen framebuffer, MetaShapedTexture will
need to have full control of the painting routines of paint nodes.
As such, expose clutter_paint_node_paint() to allow forcing a
paint nodes paint from MetaShapedTexture.

The multitexture API is not a shortcut for multiple calls
to the single texture API. It is meant to wrap calls to
cogl_framebuffer_draw_multitexture_rectangle(), which
uses the passed texture coordinates at different layers of
the pipeline.

ClutterImage is a ClutterContent implementation that
has an internally managed CoglTexture. This texture
is recreated when new image data is set.
ClutterContent implementations may have control over
the allocation of the widgets they're attached to,
through CLUTTER_REQUEST_CONTENT_SIZE. On those cases,
if the new image data differs in size from the previous
data, it is important to notify those actors about the
size change. However, currently ClutterImage does not
notify them.
With the introduction of clutter_content_invalidate_size(),
it is possible to report the size changes to attached
actors.
Adapt ClutterImage to invalidate_size() when image data
has different sizes.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/405
ClutterContent has the ability to dictate the layout of any
given actor, through the CLUTTER_REQUEST_CONTENT_SIZE request
mode.
However, there is no way for ClutterContent implementations
to notify their attached actors that the content size changed.
Add a new optional ClutterContent.invalidate_size() vfunc and
clutter_content_invalidate_size().

The helper function from gdbus-codegen broadcasts the signal emission,
but we really only care about sending it to the specific peer that
created the session. Thus, only emit the signal to the particular peer
that owns the session.

If the extension is missing, the GPU copy path would not work. The code sets
the error, but forgets to return a failure. Fix this.
While adding the necessary return FALSE, also destroy the EGL context we just
created. Code refactoring shares the destroying code.
Found by reading code.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/416
If the GPU copy path would use a software renderer, fall back to the CPU
copy path. The CPU copy path is possibly faster and avoids screen
corruption issues that were observed on an Intel Haswell desktop. The
corruption was likely due to texturing from an unfinished rendering or
memory caching issues.

Print the pixel format chosen for an output on a secondary GPU for
debugging. Knowing the format can aid in debugging e.g. red/blue channel
swaps and CPU copy performance issues.
This adds a DRM format printing helper in meta-crtc-kms.h. This header
is included in most native backend files making it widely available,
while DRM formats are specific to the native backend. It could be shared
with Wayland bits, DRM format codes are used there too.
The helper makes the pixel format much more readable than a "%x".
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
When setting up an output on a secondary GPU with the CPU copy mode,
allocate the dumb buffers with a DRM format that is advertised supported
instead of hardcoding a format.
Particularly, DisplayLink devices do not quite yet support the hardcoded
DRM_FORMAT_XBGR8888. The proprietary driver stack actually ignores the
format assuming it is DRM_FORMAT_XRGB8888 which results the display
having red and blue channels swapped. This patch fixes the color swap
right now, while taking advantage if the driver adds support for XBGR
later.
The preferred_formats ordering is somewhat arbitrary. Here it is written
from glReadPixels point of view, based on my benchmarks on Intel Haswell
Desktop machine. This ordering prefers the format that was hardcoded
before.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
These functions allow inspecting which pixel formats a CRTC's primary
plane supports. Future patches will inspect the supported formats and
pick a framebuffer format accordingly instead of hardcoding a format.
The copy list function will be used to initialize a formats list, and
the supports format function will be used to intersect that list against
another CRTC's supported formats.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
This avoids having to hardcode the same fallbacks elsewhere multiple
times when determining what formats might be suitable for a set of
CRTCs. The formats_modifiers hash table is now guaranteed to be
populated with at least something, so future code will not need to
handle it being empty.
The hardcoded fallback formats are a minimal set probably supported by
most hardware. XRGB8888 is the format that, according to ancient lore,
all DRM devices should support, especially if they don't have the
capability to advertise otherwise. Mutter also hardcodes XRGB8888 as the
GBM surface format, so it is already required on primary GPUs.
XBGR8888 matches the most common OpenGL format, sans alpha channel since
scanout hardware has not traditionally supported alpha. XBGR8888 is here
also because Mutter hardcodes that format for secondary GPU outputs when
using the CPU copy path.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
If the IN_FORMATS property is not found, copy the formats from the DRM
plane instead. This is the fallback for getting a list of formats the
primary plane supports when DRM universal planes capability is enabled.
https://gitlab.gnome.org/GNOME/mutter/merge_requests/341
Rather than picking just one format, parse and store all the formats and
their modifiers.
This gives us a list of supported formats (and modifiers) on a CRTC
primary plane. Later I will be using this list to choose a framebuffer
format instead of hardcoding it.

When profiling gnome-shell it was found that one of the main triggers
of `clutter_actor_queue_relayout` during animations was
`clutter_actor_set_margin_internal` continuously setting the same
zero margins. That's obviously pointless and also expensive. So just
avoid redundant margin changes.
This helps to further improve performance in:
https://gitlab.gnome.org/GNOME/mutter/issues/233,
https://gitlab.gnome.org/GNOME/gnome-shell/issues/349
This change previously landed as 59acb3895 and then got reverted because
it was found to make gnome-shell#517 worse. However that bug now has a
proper fix and this branch isn't really directly related so is being
reproposed...
Just move the minimal bits to this ClutterKeymapEvdev object. Much
of the functionality of a keymap is spread along ClutterSeatEvdev,
ClutterDeviceManagerEvdev and ClutterVirtualInputDevice. Future
refactors are due here.
Also, ideally keymaps are per-seat objects (at least keyboard state
is). We don't expose much info about seats altogether outside the
evdev device manager implementation. We just poke the main seat at
places, but eventually seats should be public.
We thus far have similar objects/code internal to backends. Expose the
minimum API necessary to cater for gnome-shell as a generic object.
So far only the X11 backend has an actual GObject for it, and was made
to be a subclass right away.
`distribute_natural_allocation` expects an input >= 0 of type `gint`. In
`get_preferred_size_for_opposite_orientation` it is used with an unchecked
variable `size` of type `gfloat`, which in case it is `Infinity`, gets
passed on in the macro `MAX (0, size)`. `Infinity` becomes `G_MININT`
when implicitly casted to `gint` in `distribute_natural_allocation`,
triggering the assertion `extra_space >= 0`.
The resulting warning in the log is counter intuitive and not very
helpful.
Use `float` in `distribute_natural_allocation` instead of `gint` and
assert on denormal values so we can more easily identify bugs.
Additionally change some types while at it and add a even more
expressive warning referencing the actor at one point.

This is done through gtk-shell ATM. If a window requests focus with
an invalid startup ID, just the demands-attention flag will be set.
The "did user interaction happen in between" checks are left to
meta_window_activate_full/meta_window_focus, by passing the timestamp
of the original launch request.
This version has 2 new requests:
- gtk_shell1.notify_launch notifies the compositor that the requesting
client shall launch another application. The given ID is expected to
be unique.
- gtk_surface1.request_focus notifies the compositor that a surface
requests focus due to it being activated. The given ID is passed to
this process through undetermined means, if it corresponds with a
current startup ID and there was no user interaction in between the
surface will be focused, otherwise it will demand attention.
It scaled the logical monitor rect with scale to get the stream
dimensions, but that is only valid when having
'scale-monitor-framebuffers' enabled. Even when it was, it didn't work
properly, as clutter_stage_capture_into() doesn't work properly with
scaled monitor framebuffers yet.

Commit 25f416c13d added additional compilation warnings, including
-Werror=return-type. There are several places where this results
in build failures if `g_assert_not_reached()` is disabled at compile
time and the compiler misses a return value.

`ClutterOffscreenEffect` had been getting the wrong bounding box in the
case of clones and descendents of clones, causing visibly incorrect
clipping. This was due to `clutter_actor_get_paint_box` only ever being
given the source actor during a paint (which is correct) and not the clone.
Even if we weren't painting a clone but an offscreened descendent of a
clone (like in gnome-shell's desktop zoom), we would get the wrong result.
Fortunately we don't need to know the actual clone/actor being painted so
don't need to call the problematic `clutter_actor_get_paint_box` at all.
The solution is to only keep untransformed rendering in the FBO and leave
the correct transformation for later. The correct clone/actor's
transformation is already set for us as the current cogl modelview matrix
by `clutter_actor_paint`.
Bonus optimization: This all means we don't need to keep `last_matrix_drawn`
or force a full repaint every time some part of the transformation changes.
Because the FBO contents are no longer affected by transformations. As it
should be. In other words, offscreen-effected actors can now move around
on screen without themselves being repainted.
Special thanks to Mai Lavelle for identifying the cause of the problem.

Shell is using these, which was revealed by
1bbb5c8107 breaking its build when
generating its introspection due to meta_startup_notification_get_type()
not being found.
We keep the class structs private, so in practice MetaStartupSequence
and MetaBackend can't be derived from (the are semi-private).
Make meson link libmutter using -fvisibility=hidden, and introduce META_EXPORT
and META_EXPORT_TEST defines to mark a symbols as visible.
The TEST version is meant to be used to flag symbols that are only used
internally by mutter tests, but that should not be considered public API.
This allows us to be more precise in selecting what is exported and what is
not, without the need of a version-script file that would be more complicated
to maintain.

MonitorManager was inheriting from MetaDBusDisplayConfigSkeleton, this was
causing introspection to see this like a GDBus skeleton object exposing to
clients methods that were not required.
Also, this required us to export meta_dbus_* symbols to the library, while
these should be actually private.
So, make MetaMonitorManager to be just a simple GObject holding a skeleton
instance, and connect to its signals reusing most of the code with just few
minor changes.

pkg-config files for mutter are generated using *_pkg_deps as requires, but
programs linked with libmutter doesn't need most of these private dependencies
which are only needed for building and linking mutter and its subprojects.
So list packages needed only by mutter itself inside *_pkg_private_deps and
don't expose such packages to pkg-config, but only use them at build time.

Soname of the libraries should be the major version number, while the version
triplet is currently used:

Map files were using wrong syntax (missing final `;` or invalid chars).
Also, the map files were only monitored for rebuilding, but not really used by
ld, so pass the ldflags with version-script so that private symbols are really

Some types were declared in the public headers so that g-ir-scanner
could resolve the types. This caused warnings when using
