Preparation step before splitting:
* adds project(KWIN)
* lists all KWin dependencies
KWin can be built standalone if cmake is run with:
-DKWIN_BUILD_OXYGEN=OFF
-DKWIN_BUILD_KAPPMENU=OFF
Oxygen because it needs liboxygen - for standalone clients/oxygen needs
to be moved out of KWin.
KAppmenu because it includes the DBus xml file.

Painting was already disabled in the effect inside ksmserver, thus it
was more or less dead code. Let's remove it completely.
This also allows to remove the "temporary" hack inside KWin's logout
effect.

Creates two subdirectories: plasma-workspace and plasma-desktop
plasma-workspace contains the modules that should be re-usable between
different form factors. plasma-desktop contains the modules that
are specific to the Desktop.

This is a temporary solution to have less dependencies on
KDEBASE_WORKSPACE_SOURCE_DIR. Once kde-workspace is going to be splitted
this won't work, we need a proper way to find the dbus interfaces
provided by ksmserver.
Note: for appmenu the same problem exists, but doesn't affect us once we
are splitted as we can turn off the usage through a build option. So for
a splitted kde-workspace the appmenu dependency can just be temporarily
be removed.
When moving/resizing a window we don't want the keyboard events being
passed to the Clients. Instead we want to do the normal processing.
Unfortunately moving the window through the keyboard relies on warping
the pointer which is not (yet) available on Wayland. This means that this
is not yet working, but ending through enter/escape etc. is working as
expected.
Major new functionality is xkbcommon support. InputRedirection holds an
instance to a small wrapper class which has the xkb context, keymap and
state. The keymap is initialied from the file descriptor we get from the
Wayland backend.
InputRedirection uses this to translate the keycodes into keysymbols and
to QString and to track the modifiers as provided by the
Qt::KeybordModifiers flags.
This provides us enough information for internal usage (e.g. pass through
effects if they have "grabbed" the keyboard).
If KWin doesn't filter out the key events, it passes them on to the
currently active Client respectively an unmanaged on top of the stack.
This needs still some improvement (not each unmanaged should get the
event). The Client/Unmnaged still uses xtest extension to send the key
events to the window. So keylogging is still possible.
InputRedirection keeps track of the Toplevel which is currently the one
which should get pointer events. This is determined by checking whether
there is an Unmanaged or a Client at the pointer position. At the moment
this is still slightly incorrect, e.g. pointer grabs are ignored,
unmanaged are not checked whether they are output only and input shapes
are not yet tracked.
The pointer events are delivered to the Toplevel as:
* enter
* leave
* move
* button press
* axis event
Nevertheless move events are still generated in InputRedirection through
xcb test for simplicity. They are still send to the root window, so all
windows get mouse move.
Button press and axis are generated only in the implementations of the
event handlers and delivered directly to the window, so other windows
won't see it.
Unfortunately this is extremely platform specific with code for X11 and
Wayland. But at the moment it doesn't make much sense to abstract as
Effects are the only case where a fullscreen low level input area is
used.
A small problem is also that the mouse cursor doesn't get restored and
is changed when the X11 cursor changes. This will be fixed once we start
to properly track the cursor of the individual X windows.
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.
InputRedirection forwards pointer events (currently motion, press and
release) through the EffectsHandlerImpl for the case that an effect has
intercepted pointer events.
If the KWin operation mode is not X11 only, the window for intercepting
the mouse events is no longer created.
A new AreaBasedEdge is introduced which supports the Edge functionality
by just connecting to the globalPointerChanged signal of
InputRedirection.
The AreaBasedEdges are used if KWin's operation mode is not X11 only.
This unfortunately required to change the datatype of the list of edges
in ScreenEdges. It used to be specific on the inheriting class.
So far this new class is not yet doing much. The WaylandBackend forwards
the received pointer events to this InputRedirection class. From there
signals are emitted to inform internal areas about the changes first.
The events are currently forwarded to X through the xtest extension. This
will be removed in future. Input will be forwarded directly to the
surface which wants it (no matter whether X11 or Wayland).
It's no longer needed as the OpenGLBackend has a direct rendering
detection and the remaining OpenGL2 backend aborts if the backend
uses indirect rendering. Thus the GLPlatform must always have a
direct rendering context.
