Technically the Surface itself does not have a size, it's the
ShellSurface or the size of the FullScreenShell's Output. But it
simplifies a lot if we keep track of the size in the Surface as that
way we can hide the fact which kind of Shell is used.
The user of the Surface must connect either the FullscreenShell's
Output or the ShellSurface to set the size on the Surface.
The fullscreen shell is only provided with at least Weston 1.5.
It should be checked on runtime, but that's difficult as Weston doesn't
fail if it cannot find the shell.so. So we disable it based on the
assumption that if Wayland library is not 1.5 the Weston is also not 1.5.
A Surface class is split out which holds a wl_surface and supports
attaching a buffer, setting the damage and emitting a signal when the
frame callback got called.
It doesn't come with a unit test yet as it first needs the ShmPool
and Buffer properly split out to easily set it up.
New classes Shell and ShellSurface are created. Both are in shell.[h|cpp]
to indicate their close relationship with the Shell having to create the
ShellSurface.
WaylandBackend is adjusted to hold a Shell* and ShellSurface* instead of
the lower level structs. This also required adjustements to the creation
of the Backend as it now doesn't set a default size any more. Thus the
backendReady signal may not be emitted before the initial configure
event arrived. This also makes it easier to support either the fullscreen
shell or wl_shell at the same time.
Of course a unit test is added for the two new classes. This needs to
be extended once we have more control over the mock Wayland server.
At the same time adding an autotest for the Output, moving the listener
into the Output class and providing enums for Subpixel and Transform.
KWin now requires wl_ouput interface version 2 as that allows us to emit
the changed signal in a better way.
The unit test is not yet capable of testing everything, we need a mock
Wayland server which is more flexible.
The FullscreenShell is a Wayland protocol provided by Weston to have
exactly one surface per output. This is exactly what KWin needs. So
in case the Wayland server we connect to provides the FullscreenShell
we prefer it over the normal Shell and mapping our surface as fullscreen.
The protocol is not yet part of wayland-client library, so the header
and source file needs to be generated. This is done during the build
process using the external tool wayland-scanner. The protocol
description is copied from the Westion 1.5 sources.

The Wayland::Registry class wraps wl_registry handling. It keeps track
of the interfaces in the registry and emits signals whenever a known
interface gets announced or removed. So far it only tracks the interfaces
which are used and needed by KWin.
The Wayland event queue is moved into a dedicated thread and a
new class is created for just creating the connection and listening
for events. The WaylandBackend creates the thread and uses an event
queue for the main thread.

This restores the behavior on KWin4: if I set an X property that doesn't have any data on a window, it's still information, so this makes the Xcb wrapper return an empty QByteArray that is not null.
EffectWindow::readProperty() now returns an empty QByteArray constructed the same way as it was in KWin4.

This removes all the hacks to add kwin4_effect_ to the name of the Effect
and adjusts the desktop files of the effect configuration's parent
component.
Note: the scripted effects still start with kwin4_effect_ prefix.

The Xcb::Property can wrap the xcb_get_property call and provides
convenient access methods to read the value of the reply with checks
applied. For this it provides a templated ::value method for reading a
single value or reading an array. There's also a ::toBool and
::toByteArray which performs the conversion directly with default values
for the type and format checks.
Xcb::TransientFor is changed to be derived from Property instead of
Wrapper directly, so that the reading of the property value can be
shared.
Xcb::StringProperty is a convenient wrapper derived from Property to
handle the reading of a string property providing a cast to QByteArray
operator. This replaces the ::getStringProperty from utils. Though the
separator functionality from ::getStringProperty is not provided as that
is only used in one function and handled there.
All the custom usages of xcb_get_property or getStringProperty are
replaced to use this new wrapper. That simplifies the code and ensures
that all properties are read in the same way.

So far the effects could just use the connection() and rootWindow()
provided by kwinglobals. Thus an internal detail from KWin core is
accessed directly.
To be more consistent with the rest of the API it's wrapped through the
EffectsHandler and with a convenient method in Effect.
The connection() is provided as xcbConnection() to free the very generic
name connection which could create confusion once we provide a wayland
connection to the Effects.
The rootWindow() is provided as x11RootWindow() to indicate that it is
for the X11 world.

Let's use the available API instead of duplicating code.
Nice side effect: client_machine.cpp doesn't include utils.h any more
which simplifies the unit test.

This is a specialized subclass of AbstractEffectLoader to load binary
effect plugins. It used the KPluginTrader to find all candidates to load.
The loader is able to detect incorrect ABI versions through the
pluginVersion() and uses the methods exposed by the new
KWin::EffectPluginFactory to check whether the Effect is supported and
should be enabled by default.
The unit test for this loader comes with two plugins: one is able to be
loaded and provides a supported and enabledByDefault method which can be
tweaked during the test to get all the conditions we want to test for.
The second plugin uses an incorrect plugin version and thus cannot get
loaded.
This implementation of the AbstractEffectLoader is able to to load the
scripted KWin Effects. It uses KServiceTypeTrader to find all the
candidates to load.
Effect loading gets split by the kind of effects KWin supports:
* Built-In Effects
* Scripted Effects
* Binary Plugin Effects
For this a new AbstractEffectLoader is added which will have several
sub-classes:
* BuiltInEffectLoader
* ScriptedEffectLoader
* PluginEffectLoader
* EffectLoader
The EffectLoader will be what the EffectsHandlerImpl is using and it just
delegates to the three other types of loaders. Thus the handler doesn't
need to care about the different kinds of effects. The loading is
supposed to be completely async and the EffectLoader emits a signal
whenever an Effect got loaded. The EffectsHandlerImpl is supposed to
connect to this signal and insert it into its own Effect management.
Unloading is not performed by the loader, but by the EffectsHandler.
There is one important change which needs to be implemented: the ordering
cannot be provided by the loader and thus needs to be added to the
Effects directly.
So far only the BuiltInEffectsLoader is implemented. It's not yet
integrated into the EffectsHandlerImpl, but a unit test is added which
tries to perform the various operations provided by the loader and the
BuiltInEffects. The test should cover all cases except the Check Default
functionality which is only used by Blur and Contrast effects. This
cannot be mocked yet as the GLPlatform doesn't allow mocking yet.
Only delegated to Cursor::pos() anyway, so let's just use that directly.
Fixes the annoyances of having to mock it in the unit tests which include
utils.cpp.
REVIEW: 116900
Used by Cursor to properly emit the mouseChanged signal which for
historic reasons includes the keyboard modifiers.
Again some fiddling around with the autotests and kcmrules needed to
make it compile. This needs improvement!
New inheriting class which uses the InputRedirection to track the cursor
position. It doesn't support warping of cursor.
This introduces a slight dependency loop in the startup. Cursor needs to
be created after the WaylandBackend to ensure that the operation mode is
set correctly. But the WaylandBackend itself is accessing Cursor. It
should be safe as inside the WaylandBackend it's only accessed after
callbacks.
