When drmHandleEvent() returns an error and errno is set to EAGAIN,

The prefix, if any, of a variable name often contains information about
the namespace (such as clutter_backend is the ClutterBackend, while
backend is a MetaBackend). Clean up some more inconsistencies in
meta-renderer-native.c where various variable names were egl_ prefixed
but in fact was Cogl types.

In order to eventually support multilpe GPUs with their own connectors,
split out related meta data management (i.e. outputs, CRTCs and CRTC
modes) into a new MetaGpu GObject.
The Xrandr backend always assumes there is always only a single "GPU" as
the GPU is abstracted by the X server; only the native backend (aside
from the test backend) will eventually see more than one GPU.
The Xrandr backend still moves some management to MetaGpuXrandr, in
order to behave more similarly to the KMS counterparts.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Pass the backend to a new factory function, and keep a pointer to the
monitor manager, which is accessed elsewhere in the same file instead of
fetching the singleton. The HW cursor initialization part is also made
more obvious, without depending on seemingly irrelevant clutter
features.
https://bugzilla.gnome.org/show_bug.cgi?id=785381
Move finding, opening and managment of the KMS file descriptor to
MetaMonitorManagerKms. This means that the monitor manager creation can
now fail, both if more than one GPU with connectors is discovered, or
if finding or opening the primary GPU fails.

The monitor manager instance was created and setup in one step; at
construction. This is problematic if, in the future, the monitor manager
creation can fail, as the monitor manager is created quite late.
To make it possible to in the future fail creating a monitor manager,
create the instance very early when initiating the backend, then on
post init backend setup, "setup" the monitor manager state, i.e. read
the current state and setup the stage.

Instead of passing it around or fetching the singleton, keep a pointer

Convert MetaCrtcMode from a plain struct to a GObject. This changes the

Pipewire doesn't export its version defines, so the API checks added
in commit f0c6c4eb1f effectively disable screencasting, whoops.
Breaking changes like this should disappear once the library stabilizes,
so simply define the version ourselves instead of writing a "proper"
test with AC_COMPILE_IFELSE() ...

The modifier event was only added in v3 of the client; sending it to
older clients (e.g. GStreamer waylandsink) causes them to disconnect

Send the older 'format' event to all clients, and only send the newer

People that relied on xsetwacom to configure their tablets used to get
away with this by disabling the wacom g-s-d plugin prior to running
their scripts. This is not possible anymore with mutter managing device
configuration.
Given that X11 shall not go away soon and there's a core of stubbornly
accustomed users, provide a MUTTER_DISABLE_WACOM_CONFIGURATION envvar
to provide *some* way to do this.
To keep feature parity with the Wayland backend, and
to improve the overall tiling experience with GTK apps,
add the _GTK_EDGE_CONSTRAINTS X11 atom and update it
when necessary.
https://bugzilla.gnome.org/show_bug.cgi?id=751857
Following up the previous patch, this patch makes the
Wayland backend send the edge constraints through a
custom protocol extension internal to GTK.
As it mature, we can think of upstreaming the protocol
to Wayland itself.

GTK has the ability to handle client-decorated windows
in such a way that the behavior of these windows must
match the behavior of the current window manager.
In Mutter, windows can be tiled horizontally (and, in
the future, vertically as well), which comes with a few
requirements that the toolkit must supply. Tiled windows
have their borders' behavior changed depending on the
tiled position, and the toolkit must be aware of this
information in order to properly match the window manager
behavior.
In order to provide toolkits with more precise and general
data regarding resizable and constrained edges, this patch
makes MetaWindow track its own edge constraints.
This will later be used by the backends to send information
to the toolkit.
https://bugzilla.gnome.org/show_bug.cgi?id=751857
When computing a potential match for a tiled window, there is a
chance we face the case where 2 windows really complement each
other's tile mode (i.e. left and right) but they have different
sizes, and their borders don't really touch each other.
In that case, the current code would mistakenly assume they're
tile matches, and would resize them with either a hole or an
overlapping area between windows. This is clearly a misbehavior
that is a consequence of the previous assumptions pre-resizable
tiles.
This patch adapts the tile match algorithm to also consider the
touching edges when computing the matching tile, unless:
* the window is not currently tiled (for example when computing
the tile preview)
* the window is currently resized in tandem with an existing
tile match

When a pair of tiled windows are grouped together, they
are treated as parts of a whole and interacting with one
affects the other.
Following the idea that sibling tiled windows are treated
as part of the same group, they should also be raised and
lowered together.
It is still possible to break tiled windows grouping by
simply untiling the window with the keyboard or by grabbing
and resizing or moving the window with the cursor.
This patch makes sibling tiled windows be lowered and raised
in tandem. For future reference, this behavior is documented
in [1].

There is a variable in meta_window_edge_resistance_for_resize
that isn't really helpful: it just assumes TRUE, and is passed
to apply_edge_resistance_to_each_side.
This patch removes that useless variable and simply pass TRUE
instead.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
When windows are tiled, it improves the interaction with
them when they have a set of snapping edges relative to
the monitor. For example, when there's a document editor
and a PDF file opened, I might want to rescale the former
to 2/3 of the screen and the latter to 1/3.
These snapping sections are not really tied to any other
window, and only depend on the current work area of the
window. Thus, it is not necessary to adapt the current
snapping edge detection algorithm.
This patch adds the necessary code in edge-resistance.c
to special-case tiled windows and allow them to cover
1/4, 1/3 and 1/2 (horizontally) of the screen. These
values are hardcoded.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
After the introduction of the possibility to resize tiled windows,
it is a sensible decision to make windows aware of their tiling
match. A tiling match is another window that is tiled in such a
way that is the complement of the current window.
The newly introduced behavior attepts to make tiling as smooth as
possible, with the following rules:
* Windows now compute their tile match when tiling and, if there's
a match, they automatically complement the sibling's width.
* Resizing a window with a sibling automatically resizes the sibling
too to be the complement of the window's width.
* It is not possible to resize below windows' minimum widths.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
Now that tiled windows are resizable, the user may grow a tiled
windows until it covers the entire work area. As this makes the
window state mostly indistinguishable from maximization, avoid
subtle differences by properly maximizing the window in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=645153
Currently tiled windows are not resizable and their size is fixed
to half the screen width. Adjust the code to work with fractions
other than half, and allow users to adjust the split by dragging
the window edge that is not constrained by a monitor edge.
Follow-up patches will improve on that by resizing neighboring
tiled windows by a shared edge, and making the functionality
available to client-side decorated windows implementing the
new edge constraints protocol.
Now that the preview tile mode has been split from the window's
tile_mode property, it is much more natural to pass the requested
tile_mode to the tile() function instead of setting it externally
and calling the function to apply the state.
