10b0351a59 Add support for rudimentary fractional scaling
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.

b64c69e4bc logical-monitor: Make scale a float
To support fractional scaling, the logical monitor scale must be stored
as a float. No other functional changes is part of this commit.

1bb0e18042 monitor-manager/xrandr: Allow configuring scales on X11 too
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.

0608ae2d4e monitor-config-store: Replace key when replacing config
g_hash_table_insert() doesn't replace the key. This was a problem
because the key was owned by the value inserted into the hash table, so
when a value was removed, the key was freed, meaning that the key in
the hash table was no pointing to freed memory. Fix this by using
g_hash_table_replace() instead, which work the same except that it
replaces the key with the one passed. This means that the key of a
value in the hash table is always the key owned by the value.

740436ab4d monitor-config-store: Add support for saving configuration
When told to, MetaMonitorConfigStore will save the current
configuration state by replacing the monitors-experimental.xml file
(while backing a backup).

1e2266aa47 monitor-config-store: Add support for transform in config
Adds a <transform> element to <logicalmonitor>. It has two possible sub
elemenst: <rotation> which can be normal, right, left or upside_down,
and <flipped> which can either be true or false.

ac68631f4c monitor-config-store: Don't crash when cleaning up after failing to load
The logical monitor config array ownership was transferred to the
config object when it was created, but was not unset when the config
verification failed, causing the clean up path for invalid configs to
try to clean up the same list again.

8163ca6821 Add support for scaled logical monitor framebuffers
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).

ee32ca3efe monitor-store: Support configuring logical monitor scale
Add support to configure the logical monitor scale. With this, it

753e9c65a1 meta-monitor-config: Pass logical monitor scale via config
The default (calculated) scale is derived from the output, but
ultimately set via the monitor scale. This will enable config files to
override the scale. Yet to be done is handling when a scale is not
supported by a backend (i.e. the X11 backend).

1ad386bc28 Introduce MetaMonitorConfigStore
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.
