Turn MetaOutput into a GObject and move it to a separate file. This
changes the storage format, resulting in changing the API for accessing
MetaOutputs from using an array, to using a GList.

When we update state, we might not have set the current config yet (for
example if the Xrandr assignment didn't change), so pass the monitors
config we should derive from instead of fetching it from the monitor
config manager.

When headless, we don't have any logical monitors to derive a screen
size from, but we can't set it to empty as that will cause issues with
the clutter stage, UI widget layout and other things. To avoid such
issues, just fall back to a 640 x 480 screen size when headless.

This will allows us to support the XF86Display key present on some
laptops, directly in mutter. This is also known, in evdev, as
KEY_SWITCHVIDEOMODE.
The common usage for this key is to alternate between a few well known
multi-monitor configurations though these aren't officially
standardized. As an example, Lenovo documents it as:
"Switches the display output location between the computer display
and an external monitor."
On this patch, we're just introducing the configurations that have been
implemented in g-s-d until now, which go a bit beyond the above
description.

Differentiate between non-interlaced and interlaced modes. This is done
by appending an "i" after the resolution part of the mode ID, and
adding a 'is-interlaced' (b) property to the mode properties.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
This changes the API to pass supported scales per mode instead of
providing a global list. This allows for more flexible scaling
scenarious, where a scale compatible with one mode can still be made
available even though another mode is incompatible.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When the logical layout mode is used, allow configuring the scaling to
be non-integer. Supported scales are so far hard coded to include at
most 1, 1.5 and 2, and scales that doesn't result in non-fractional
logical monitor sizes are discarded.
Wayland outputs are set to have scale ceil(actual_scale) meaning well
behaving Wayland clients will provide buffers with buffer scale 2, thus
being scaled down to the fractional scale.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
This commit makes it possible to configure logical monitor scale also
when running on top of an X11 server using Xrandr. An extra property
'requires-globla-scale' is added to the D-Bus API is added to instruct
a configuration application to only allow setting a global logical
monitor scale.
This is needed to let gsd-xsettings use the configured state to set a
XSettings state that respects the explicit monitor configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of using a environment variable, add a new 'experimental
feature' gsetting keyword "monitor-config-manager" that enables the use
of the new MetaMonitorConfigManager. This commit also makes it possible
to switch between the two systems without restarting mutter.
The D-Bus API is disabled when the experimental feature is not enabled,
and clients trying to access it will get a access-denied error in
response. A new property 'IsExperimentalApiEnabled' is added to let the
D-Bus client know whether it is possible to use the experimental API or
not.

This commit adds support for rendering onto enlarged per logical
monitor framebuffers, using the scaled clutter stage views, for HiDPI
enabled logical monitors.
This works by scaling the mode of the monitors in a logical monitors by
the scale, no longer relying on scaling the window actors and window
geometry for making windows have the correct size on HiDPI monitors.
It is disabled by default, as in automatically created configurations
will still use the old mode. This is partly because Xwayland clients
will not yet work good enough to make it feasible.
To enable, add the 'scale-monitor-framebuffer' keyword to the
org.gnome.mutter.experimental-features gsettings array.
It is still possible to specify the mode via the new D-Bus API, which
has been adapted.
The adaptations to the D-Bus API means the caller need to be aware of
how to position logical monitors on the stage grid. This depends on the
'layout-mode' property that is used (see the DisplayConfig D-Bus
documentation).
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Make the concept of maximum screen size optional, as it is not
necessarily a thing on all systems (e.g. when using the native backend
and stage views).
The meta_monitor_monitor_get_limits() function is replaced by a
meta_monitor_manager_get_max_screen_size() which fails when no screen
limit is available. Callers and other users of the previous max screen
size fields are updated to deal with the fact that the limit is
optional.
The new D-Bus API is changed to move it to the properties bag, where
its absence means there is no applicable limit.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Add a new D-Bus API that uses the state from GetCurrentState to
configure high level monitors, instead of low level CRTCs and
connectors. So far persistent configuration is not implemented, as
writing to the configuration store is still not supported.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Replace the 'scale' of an output with a vfunc on the MetaMonitorManager
class that takes a monitor and a monitor mode which calculates the
scale. On X11 this always returns 1, on KMS, the old formula is used.
On the dummy and test backends, the already configured values are
returned.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
A MetaOutput is a connector, not exactly a monitor or a region on the
stage; for example tiled monitors are split up into multiple outputs,
and for what is used in input settings, that makes no sense. Change
this to use logical monitors instead of outputs.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Expose via a new API whether the transform on a logical monitor is
handled by the backend. This was previously only exposed only in the
native backend. This will be used to emulate not supporting transforms
in the backend in the nested backend.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
MetaMonitorConfigStore provides an XML storage mechanism for
MetaMonitorConfigManager. It stores configuration files defined in the
same level as the MetaMonitorsConfig format, i.e. refers to high level
"monitors" and "monitor modes" instead of connectors and CRTCs.
Only reading custom files are implemented and so far unused.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Handle headless setup gracefully by having no logical monitors. This
commit only makes the monitor management code deal with it; other areas
may still not be able to handle it.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Move the UpClients notify::lid-is-closed signal handling into
MetaMonitorManager, and put the getter behind a vfunc. This means
Placing it behind a vfunc allows custom backends to implement it
differently; for example the test backend can mock the state.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The new monitor configuration system (MetaMonitorConfigManager) aims to
replace the current MetaMonitorConfig. The main difference between the
two is that MetaMonitorConfigManager works with higher level input
(MetaMonitor, MetaMonitorMode) instead of directly looking at the CRTC
and connector state. It still produces CRTC and connector configuration
later applied by the respective backends.
Other difference the new system aims to introduce is that the
configuration system doesn't manipulate the monitor manager state; that
responsibility is left for the monitor manager to handle (it only
manages configuration and creates CRTC/connector assignments, it
doesn't apply anything).
The new configuration system allows backends to not rely on deriving the
current configuration from the CRTC/connector state, as this may no longer be
possible (i.e. when using KMS and multiple framebuffers).
The MetaMonitorConfigManager system is so far disabled by default, as
it does not yet have all the features of the old system, but eventually
it will replace MetaMonitorConfig which will at that point be removed.
This will make it possible to remove old hacks introduced due to
limitations in the old system.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The function meta_monitor_manager_read_current_config() was renamed to
meta_monitor_manager_read_current_state() as it does not read any
configuration, but reads the current state as described by the backend.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In preparation of replacing the configuration system with one working
with high level monitors instead of low level outputs etc, move
configuarion handling code into obviously named function (containing
the word 'legacy'.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Don't deal with adding/removing tiled Xrandr monitors in the generic
backend, but leave it to the Xrandr backend. The tiled monitor will
itself notify the backend when such a monitor is added and removed.
Tiled Xrandr monitors are now based no MetaMonitor instead of
MetaLogicalMonitor. This means that mirrored tiled monitors will now be
represented correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Generate a set of "monitors" abstracting the physical concepts. Each
monitor is built up of one or more outputs; multiple outputs being
tiled monitors. Logical monitors will later be built from these.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
The MetaMonitorMode referred to the mode of a CRTC, and with the future
introduction of a MetaMonitor, theh old name would be confusing.
Instead call it what it is.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Put the monitor xinerama index in a separate struct that is attached to
the logical monitor using g_object_set/get_qdata(). Eventually this
should be moved to some "X11 window manager" object, but lets keep it
in MetaScreen until we have such a thing.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using
indices, put it in a GList, and use GList iterators when iterating and
alternative API where array indices were previously used.
This allows for more liberty regarding the type of the logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Change meta_monitor_manager_get_logical_monitor_at() to use floats,
replace users of meta_monitor_manager_get_monitor_at_point() to use the
API that returns a logical monitor and remove the now unused function.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Move the last piece of monitor grid getter API to the monitor manager
away from MetaScreen. The public facing API are still there, but are
thin wrappers around the MetaMonitorManager API.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Turning a rectangle into a logical monitor also has nothing to do with
the screen (MetaScreen) so move it to MetaMonitorManager which has that
information.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
This is the current equivalent of looking up the logical monitor in the
logical monitor array using the number, but eventually that will be
deprecated, and before that done differently, so add a temporary helper
for the places that has not been ported yet.
