Summary:
This call is added for the window rules kcm which has a detect
functionality. As that detect functionality cannot query any Wayland
windows we need to have some functionality in KWin core. Furthermore
this allows to simplify the code in the kcm as all the custom X11
interaction can be removed. KWin internally has the functionality to
find a window at a given position.
From a security perspective adding this dbus method is fine as the user
stays in control of the functionality. It requires active click to
select a window.
The new dbus call is already used in the rules kcm replacing the
X11 based detect functionality. That a detect is now able to get
information for both X11 and Wayland windows. So far only X11 windows
on X11 were supported. So this fills an important gap in the Wayland
offerings. It should now be possible to create rules for Wayland
windows (though may not be fully functional).
Test Plan: Run the kwin_rules_dialog and it detected the window correctly

Summary:
The idea behind the debugging console is to have a feature comparable
to xprop and xwininfo just for Wayland. We cannot have command line
utils as that violates the security restrictions, thus it needs to be
exposed directly in KWin.
The debugging console is invoked through DBus:
qdbus org.kde.KWin /KWin showDebugConsole
This opens a window with a tree view. The DebugConsoleModel which is
used by the tree view groups all windows into four categories:
* x11 clients (that is Workspace::clientList() and Workspace::desktopList())
* x11 unmanaged (Workspace::unmanagedList())
* wayland shell clients (WaylandServer::clients())
* wayland internal clients (KWin's own QWindows - WaylandServer::internalClients())
Each window is a child to one of the four categories. Each window itself
has all it's QProperties exposed as children.
This allows to properly inspect KWin's internal knowledge for windows and
should make it easier to investigate problems. E.g. what's a window's
geometry, what's it's window type and so on.
The debugging console is intended as a developer tool and not expected to
be used by users. That's why it's invokation is rather hidden. Due to
the fact that it's internal to KWin it results in:
* no window decoration
* stealing keyboard focus
* no way to resize, close, move from KWin side
* rendered above all other windows
There is a dedicated close button to get rid of it again. While the
console is shown it's hardly possible to interact with the system in
a normal way anymore. This is something which might be improved in
future.
At the moment the model is able to update when windows are added/removed,
but not yet when a property changes. Due to the lack of interaction with
the existing system, that's not a high priority at the moment, but can
be added in future.

Nobody is interested in whether the Abilities are supported.
There is one method in KWin core checking for the colors
supported by the currently loaded decoration:
Workspace::decorationSupportedColors
This method is not called from anywhere inside KWin, but is
part of the D-Bus interface, though nobody in KDE's repository
is calling it [1].
As it is part of public API the Abilities are only deprecated
and scheduled for removal with the next big break.

The supportInformation is extended to also read the properties
on all effects. In addition each effect can be queried just for
itself through D-Bus, e.g.:
qdbus org.kde.kwin /KWin supportInformationForEffect kwin4_effect_blur
All effects are extended to provide their configured and read
settings through properties. In some cases also important
runtime information is exposed.

BUG: 305338
FIXED-IN: 4.9.1
As discussed on the mailinglist [1] the tiling support is
removed from KWin. The main reasons for this step are:
* it is unmaintained
* it is a mode not used by any of the core KWin team
* original developer said at Akademy 2012 that he is not
interested in picking up the work again
* tiling has quite some bugs, e.g. multi screen not supported
* is conflicting with other concepts in KWin, e.g. activities
There is ongoing work to get tiling supported through a KWin
script, which is a preferred way as it does not influence the
existing C++ code base.

Effects can specify their minimum requirements in their
desktop file:
* OpenGL
* OpenGL 2 (GLSL required)
* Shaders (either ARB or OpenGL 2)
The configuration module uses this information in combination
with which backend KWin is currently using. So if e.g. OpenGL
is used and an effect requires OpenGL 2 a detailed error
message can be showed that OpenGL 2 is required.

Instead of getting the information from CompositingPrefs
the running KWin instance is queried through D-Bus.
In general the running KWin should have more information
about whether Compositing will work or not.
This means the kcm no longer has to link OpenGL.
REVIEW: 104753
The method is nowhere inside KWin called, nor used as a slot.
It's also not used from any of the KCMs and the method does not
do what the name says. It just shows and hides a window as big
as the screen geometry.
REVIEW: 104418
This adds extensive support information about the running instance
by printing out all used options, the compositing information
including GL platform, loaded effects and active effects.
The debug output can be retrieved through D-Bus:
qdbus org.kde.kwin /KWin supportInformation
or through a KWin Script (use desktop console):
print(workspace.supportInformation())
REVIEW: 104142
this implements dbus methods in kwin for saving & restoring activities.
internally, kwin creates "sub-sessions" in kwin and ksmserver to
represent the saved activities. ksmserver doesn't need to know what
activities are :)
at the moment the code includes some fake information; it will be
changed to use the real stuff once the activities service code is in.

This commit merges the kwin-tiling branch. Ideally it shouldn't break anything and add a few features ;-)
It was applied as a patch. Do not attempt to merge the branch directly, it has a few issues.
This feature is currently experimental, although it hasn't crashed in quite a long time. It lacks some features and probably leaks some memory. Fixes will be on the way.

from David. Due to an elusive bug somewhere in kdelibs we have not been
able to find out how to fix the issues that some people were having.
There seems to be a race condition as I cannot reproduce at all, David
can reproduce sporadically and some reporters can always reproduce.
This commit attempts to also keep the code style changes that were made
at the same time as the original commit as well as some minor bug fixes
that were made between then and now. Hopefully I didn't miss anything.
We will be revisit this in KDE 4.3.

Also fixed a little bug in kcmkwincompositing (dropdowns on the general tab were not updated correctly) and cleaned up the code a bit (removed a few unneeded function calls and stale connects).
See the conversation on the mailing list ("Patch for bug 174769", http://lists.kde.org/?l=kwin&m=122696916611602) for further information.
