Add support to configure the logical monitor scale. With this, it
becomes possible to override the automatically calculated scaling
number per logical monitor.
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
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).

In some cases the hardware cursor is invisible when Mutter is launched from the
TTY, due to drmModeSetCursor2 failing without a fallback being set.
This patch captures the return value of drmModeSetCursor2 and in case of an
error, enables the texture based fallback. It adds a `broken` state, that is
checked in should_have_hw_cursor() and
meta_cursor_renderer_native_realize_cursor_from_*() to avoid copying every
cursor into a gbm buffer when we know it will fail every single time.

Quick motions can come across as too fast (or slow) if it crosses outputs
with different scales. If this happens, rebuild the motion delta applying
the scale that applies to each logical monitor the pointer is crossing.
https://bugzilla.gnome.org/show_bug.cgi?id=778119
To allow for more natural pointer movements from relative pointer
devices (e.g. mouse, touchpad, tablet tool in relative mode, etc), scale
the relative motion from libinput with the scale of the monitor. In
effect, this means that the pointer movement is twice as fast (physical
movement vs numbers of pixels passed) as before, but it also means that
the same physical movement crosses the distance in a GUI no matter if
it is on a HiDPI monitor or not.

Clutter's evdev input backend has no support for setting double
click timeout set by gnome-settings-daemon. This results in
touchpad click events timing out on wayland, because the
default timeout value wasn't enough.
This patch moves timeout setting to mutter and removes X11
backend specific setting from clutter.
https://bugzilla.gnome.org/show_bug.cgi?id=771576
The code calculating the output scale involves calculations around pixel
and mm sizes, however we do compare post-transformation pixel sizes to
untransformed mm sizes, which breaks the DPI calculations. Fix this by
transforming back pixel sizes back to untransformed.
While we're at it, actually compare the output height to HIDPI_MIN_HEIGHT
instead of its width, it seems right according to the #define name and
comment.

When a state changed, e.g. a window went from unfullscreen to
fullscreen, always sync the window geometry, otherwise a compositor
application (e.g. gnome-shell) might end up with an unfinished window
state transition effect.
Without always syncing, the compositor plugin will see a 'size-change'
event, as a result of the state change, but if the size didn't change,
it would never see the 'size-changed' event. If an effect, for example
gnome-shell's fullscreen effect, is triggered on 'size-change' it might
rely on the actual size change to not get stuck. This commit allows it
to have this dependency.
This fixes a bug where a fullscreen effect gets "stuck" when a window
goes fullscreen without changing the window geometry.

The mitigation to avoid missing EDID blob was incorrect; the reason it
sometimes failed to read was a race between different applications all
trying to read the EDID at the same time. E.g. gnome-shell as GDM would
at the same time as the session gnome-shell try to read the EDID of the
same connector at the same time, triggering a race in the kernel,
making the blob reading ioctl occationally fail with ENOENT.
Remove this mitigation, as it didn't really mitigate anything; the race
could just as well happen when doing the actual read later.
https://bugzilla.gnome.org/show_bug.cgi?id=779837
When mutter is paused (i.e. not the DRM master), stop listening on
hotplug events. Instead read the current state and set modes when
resumed.
This avoids a race condition in the drm API which currently only
manages to properly deal with one application querying the EDID state
at the same time when there are multiple mutter instances running at
the same time (e.g. gnome-shell driving gdm at the same time as
gnome-shell as the session instance).

If the dnd window ends up lower in the overall stack than the window
it's supposed to fence, the drop might end up in some other window
underneath the expected target window.
Maps and raises the dnd window each time it's shown so that it's always
placed above.

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
When no output was specified, the screen limit was used to calculate the
aspect ratio. The screen limit, however, is either just an arbitrary
number if no screen limit is applicable, or a hardware graphics buffer
limit, which has nothing to do with anything actually displayed. Change
it to use the screen size instead, to get something that makes more
sense when no output is found.
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
Previously, the size of the logical monitor was derived directly from
the tiling information. This works fine until we add transformations,
or set modes with a dimension different from the resulting resolution
when tiled. Fix this by traversing the assigned CRTC rects, as these
are already transformed by the configuration system.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
By setting the environment variable MUTTER_DEBUG_TILED_DUMMY_MONITORS
to "1", the dummy MetaMonitorManager backend used when running mutter
nested will create tiled monitors instead of single-output/CRTC
monitors. This makes it possible to test tiled monitor configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Refactor monitor generation by splitting the generation of modes, CRTCs
and outputs into a separate function. A side effect is that each output
will have its own set of possible modes.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
This will be used to invert the transform in the nested mode, making it
possible to test offscreen texture based transform using the nested
backend.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Split up logical monitor cration into derived (when derived from
current underlying configuration) and non-derived (when creating from a
logical monitor configuration). This avoids that type of logic in the
logical monitor creation function.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
Add support for non-tiled monitor modes on tiled monitors. This is done
by adding all the other supported modes, except the modes with the
same resolution as the tile dimensions.
https://bugzilla.gnome.org/show_bug.cgi?id=779745
When adding a monitor and all its outputs, don't try to set the logical
monitor of the outputs CRTC if none was assigned. This might happen if
a tiled monitor only uses a subset of the connectors it are connected
via.
