Since commit 6b5cf2e, we keep override redirect windows on a layer
above regular windows in the clutter actor scene graph. In the X
server, and thus for input purposes, these windows might end up being
stacked below regular windows though, e.g. because a new regular
window is mapped after an OR window.
Fix this disconnect by re-stacking OR windows on top when syncing the
window stack with the compositor.

When verifying if a configuration is applicable, don't set it as
current when applying succeeded, or else reverting to a previous
configuration doesn't work after having verified.

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
To be more flexible without having to change any D-Bus type signatures
in the future, replace the 'uint' flags value (currently determining
whether a mode is current and/or preferred) with a variant lookup table.
The keys 'is-current' (b) and 'is-preferred' (b) replace the existing
flags.

To be able to add more modes types that happen to have the same
resolution and refresh rate, change the API to specify modes using an
ID string. The ID string is temporary, and only works for associating a
mode for the monitor instance that it was part of.

When calculating sizes given some size and a fractional logical monitor
scale with precision loss, round the result of the floating point
calculation to the closest integer, as otherwise we might end up with
result smaller by 1 if there was a loss of precision when calculating
the scale.

To be able to render the pointer cursor sprite at sub-(logical)-pixel
positions, track the pointer position using floats instead of ints.
This also requires users of the cursor sprite rect to deal with
floating points, when e.g. finding the logical monitor etc.

When fractional scaling is used, damage and paint clip region is tracked
in stage coordinate space using integers might end up missing some
pixels when the border ends up on half pixels. Change the damage
tracking and clip regions to be in buffer coordinates so we can align
damage on physical pixel borders.
However, just using rounding up to the next physical pixel results in
glitches. To avoid this, extend the damage by one logical pixel in all
directions, but still (scissor) clip the drawing to the non-extended
region, as otherwise drawing the damaged regions will result in
incorrect pixels on the right and bottom edges of the clip region. It is
possible that there are better ways to do this, which can be explored in
the future.

We always hit non-fractional floats here because the stage views are
always made so that they are aligned on integer positions with integer
sizes, but there is no reason to go float -> int -> float when
calculating the viewport.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When passing scales over D-Bus, we'll loose some precision. To set the
correct scale, use the configured scale and look up the one actually
supported by the monitor mode, and use that. To match the supported one
with the configured one, the difference must be within rounding error
range.

We manually scaled pointer motions when they travel over a scaled
monitor. When a stage view of a monitor is also scaled, in practice this
meant we scaled twice. Avoid this by only manually scaling the pointer
motion when stage views are not scaled.

Make clutter_stage_capture() work if views are scaled. This needs
adaptations on the using side to deal with the cairo surface device
scale that is used to communicate the scale used when capturing.
https://bugzilla.gnome.org/show_bug.cgi?id=765011
When using logical sized monitors we are allowed to use fractional scaling
but only if the resulting scaled logical monitor size is in integer form.
So, in order to get this, we allow to scale the monitor to up to
8 fractional values per integer, doing some computation in order to
fetch the nearest values which are closer to the scaling factors we can
permit.
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
To support fractional scaling, change the stage view scale to be a
float instead of an int. Also change the places where it is retrieved
and used when scaling things.

Previously gnome-shell listened on the Xft Xsettings via GTK+s
GtkSettings to get the font DPI setting. The Xsetting might not
be what we want, and we should not rely on Xsettings when we don't need
to, so lets manage it ourself.

The caller in clutter really expects an error if fd==-1, so make
sure we set one here. Otherwise we get a nice crash in addition to
the failure to open the /sys file. Also, retry on EINTR.

Window moving and resizing depends on the `meta_wayland_seat_get_grab_info`
function succeeding. At the moment, tablet tools do not generate implicit
grabs like the pointer and touch. This commit adds the necessary elements
to track implicit grabs and retrieve their information.

These should be set one, but just set the master to be the slave
pad device. We are passively grabbing the pad device, so this is
consistent with active grabs on slave devices. Besides, pads are
paired to the VCP, which is not really truthful.

throttling applies for these events.

When building against a glib-genmarshal from GLib 2.54 we can use the
`--prototypes` command line argument to generate the prototypes for the
marshallers in the C source, and avoid a missing-prototypes compiler
warning.
With GLVND, whenever we have both Mesa's and NVIDIA's drives installed
in the system, initializing the GBM backend will always succeed,
regardless of what GPU you have on your system.
This is due to GBM's software rendering fallback.
It seems better to initialize the EGLDevice backend first, which will
fail to find a device match when given a non-NVIDIA GPU.

When the number of (static) workspaces decreases, we relocate windows
from extra workspaces before removing them. As removing a non-empty
workspace is not allowed, we assert that it doesn't contain any windows
before removing it.
However that assert is
- pointless, because meta_workspace_remove() already asserts that
the workspace is empty
- wrong, because even empty workspaces contain windows that are set
to show on all workspaces
Simply drop the assert to avoid a crash when trying to remove a workspace
while on-all-workspaces windows are present.

Wacom's display tablets typically do not have (0,0) coincident with the top
left corner of the screen. This "outbound" area must be taken into account
when setting the area or else an unexpected offset of the pointer will
occur.

While it doesn't make sense to set a window as transient to
itself, our existing check whether making a window transient
doesn't cover it, so it's still possible to create an infinite
loop.

It is possible to interpret the ammount of padding provided to the
*_set_tablet_area functions in two different and incompatible ways. The X11
backend effectively treats them as being input-centric (i.e., the padding
defines the size of the "dead zone" on the tablet) while the native backend
has an output-centric viewpoint (i.e., the padding defines the size of the
"dead zone" on the display) viewpoint. This difference in opinion causes the
cursor offset to change when switching between Xorg and a Wayland sessions.
The calibration utility within g-c-c does its calculations with an input-
centric viewpoint, so this patch modifies the native backend to work
correctly with these values. To change viewpoints, we can simply invert
the scale and negate the offset. It should be noted that this function
also forgot to apply scaling to the offsets (as required by the matrix
transform done by libinput) which would have further compounded the
cursor offset issue under Wayland.

It would only allow to alternate between the logical monitors, we actually
want to return NULL here so it can cycle to the whole span of monitors.

Instead of checking all MetaMonitors in the monitor manager, we want to
look (as the function name says) in the MetaMonitors contained in the
given logical monitor.
Otherwise, it will return TRUE for every logical monitor, given we are
querying for an existing EDID.
