As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.
[1] QElapsedTimer around the loading code, start kwin five times, take
average.

Most effects had a "collection" for one action. We don't need the
action collection, all it was used for is setting the object name.
With the removal of KActionCollection the effects do not need to link
XmlGui any more, though the dependency is still pulled in through
plasma.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
With the removal of BoxSwitch all effects which want mouse events use the
fullscreen input window. The available functionality is too complex both
in EffectsHandler and in the Effects.
With this change only fullscreen input windows are supported and all
effects share the input window. This means there is at maximum one input
window. This simplifies the code in the Effects as they don't have to
keep track of the window they created any more. In EffectsHandler it
means that only one window needs to be created, destroyed and raised.
Also it means that we can properly react on screen size changes which had
been ignored in the past. Also quite some roundtrips to X are no longer
needed as we do not need to query the window geometry when creating the
input window.

Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
The main difference is that the activation of an edge is no longer
broadcasted to all effects and scripts, but instead a passed in slot of
the Effect/Script is invoked.
For this the EffectsHandler API is changed to take the Effect as an
argument to (un)reserveElectricBorder. As callback slot the existing
borderActivated is used.
In addition the ScreenEdge monitors the object for beeing destroyed and
unregisters the the edge automatically. This removes the need from the
Effect to call unregister in the dtor.

FIXED-IN: 4.11
In effects it's obvious that compositing is enabled, so specifying the
translucent element is no problem.
In tabbox a context property "compositing" is injected which decides
whether "translucent" or "opaque" elements should be used. Here the
translucent elements are only used if the Blur effect is available - for
this a new Effect::Feature Blur is introduced and in addition it is
tested whether the theme provides the translucent element.
Also the masking is adjusted to ensure that only the shadow is not
blurred.
Reason for this change is that Plasma theme seems not always to pick up
whether compositing is used when used from inside KWin. It does not cover
the Desktop Change OSD which uses PlasmaCore.Dialog and there we cannot
(yet) inject that we use compositing.
Overall I'm quite unhappy with this patch and I do hope we can fix it in
the proper place in the lifetime of 4.10 and revert this patch.

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
