If the wl_surface resource happens to be destroyed before any other
role resource, the destructor for the latter will attempt to
access/modify random memory.
Fix this by ensuring the associated resources are destroyed on the
wl_surface destructor, this will free all associated memory and
remove the resources ahead of their imminent destruction.

In 3.16, GDM keeps a login screen running on vt1.
This login screen starts an Xwayland instance.
Since it's the first X server to start, it gets
the prized :0 display number.
This commit works around that problem, for now,
by having GDM's display number start at 1024.

With all input events being handled through clutter, this only confuses
things, and most nominally, coerces touch events through places we didn't
intend to, like the window frame.
This makes again all touch events only handled in the passive grab on X11,
while the rest stays pointer (emulated) only.
https://bugzilla.gnome.org/show_bug.cgi?id=745335
On startup, the cursor is kept hidden if there's any touchscreen available.
If the device that was last interacted is removed, we check on available
pointing devices though, so we don't possibly hide the pointer if there are
further mice/touchpads/etc.
Devices being added don't update cursor visibility, we wait for the user
interacting with those instead.

On X11, calling this function on meta_display_handle_events() will not catch
mouse events happening over clients, so poke directly in the backend for
XI_DeviceChanged events, which mutter will get on device switches.
The code has been slightly refactored so we deal with XIEvents at a single
handle_input_event() function.
https://bugzilla.gnome.org/show_bug.cgi?id=712775
This function can be used to trigger changes depending on the device type
that is currently emitting the events. So far, it is used to switch cursor
visibility on/off on touchscreen interaction.
A "last-device-updated" signal has also been added, in order allow hooking
other behavior changes (eg. OSK) when the last device changes.

Since commit 6e06648f7, we start out with the invisible frame parts
only, and then add the unconstrained rect's height (which consists of
the visible parts of both frame and client window) *unless* the window
is shaded. While we indeed don't want to add the client height in that
case, we need to explicitly include the visible frame parts now.

There is no good reason to do so, besides a nice way to check whether
a particular button is enabled. However there are legitimate reasons
for overdrawing like box-shadows or outlines, so remove the clip.
The initial pointer position is set by clutter. At the moment it
is the point 16x16 on the screen. But this point is not always
in the visible area on monitors (the monotors can be arranged in
many different ways).
https://bugzilla.gnome.org/show_bug.cgi?id=745752
Otherwise the pointer might be "lost" outside the visible area. Note
that the constraining code only ensures the pointer doesn't leave the
visible area but if the pointer is already outside because the rug was
pulled under it then it doesn't do anything.

The timer to blacklist the window from frame sync is set at the time of
issuing the sync request, but not removed until the client replies to
the most recent wait serial.
This means that if the client is slowly catching up, the timeout would
fire up regardless of the client slowly updating the alarm to older
values.
Fix this by ensuring the timeout is reset everytime the sync request
counter is updated, to acknowledge the client is not irresponsive,
just slow.

MetaWaylandFrameCallback has been added a surface field, which is then
checked when destroying the surfaces. This prevents unintended callbacks
to run after a surface has been destroyed.

Implicit conversion from int to float is not supported by
GLSL ES.
Fixes:
(gnome-shell:8954): Cogl-WARNING **: Shader compilation failed:
1:2: P0004: High precision not supported, instead compiling high precision as medium precision
4:17: S0001: Type mismatch in arithmetic operation between 'int' and 'float'
when one trigger the overview mode on Mali 400 r1p1 GPU.

In order to switch to the correct surface actor scale given the monitor
the surface is on, without relying on the client committing a new state
given some other side effect, sync the surface actor state when the main
monitor associated with the corresponding window changed.
https://bugzilla.gnome.org/show_bug.cgi?id=744933
Since the surface actor knows more about how it draws itself, instead of
pushing texture state (buffer and scale), input region and opaque region
from MetaWaylandSurface after having transformed into what the surface
actor expects, make the surface actor set its own state given what state
the Wayland surface is in.

DRM objects like connectors and encoders might change at any time, in
particular they might become invalid between drmModeGetResources() and
getting the actual objects in which case they'll be NULL. Be defensive
against that.
Note that, if this happens, we should get another udev event soon
which will cause us to update our state.

To make the nested compositor mode work again after "backends/native:
Calculate the output scale in here", set the scale when creating the
dummy output.

Doing this on manage() allows the common MetaWindow initialization to
do the right thing for popups like setting skip_taskbar and
skip_pager.
In particular this avoids gnome-shell's app tracker to create a new
ShellApp instance for every popup.

Before commit ac448bd42b the pointer,
keyboard, and touch objects were initialized when the seat was created.
Now they're initialized later, when the clutter device manager finds and
loads them.
This commit makes sure we don't try to access those objects if they
aren't initialized.

The wayland seat event handlers get sent events that
aren't strictly interesting to them (such as events for
hardware devices the seat doesn't support and events for
virtual devices that the seat needs to ignore).
This commit makes sure all uninteresting events get ignored.
Kerbel Space Program, and perhaps some other SDL-based programs, use
a really dumb way of specifying icons, which is totally
non-standards-compliant.
The ICCCM specifies that the icon_pixmap field of WM_HINTS should be a
1-bit-deep Pixmap, but we've seen applications set it to a pixmap of the
root depth as well, so we support that.
Kerbel Space Program seems to use it with a 32-bit depth Pixmap,
signifying ARGB32 (which it is), along with a 1-bit icon_mask, which
crashes us.
Keep in mind that Pixmaps, by definition, have no Visual attached, so
we simply have to make a guess at the correct visual based on the
depth. Do that by assuming that a depth-32 visual always means ARGB32,
which is a pretty safe bet.
