General handling for mouse driven focus and auto raise should and can
be shared between Client and ShellClient. Thus the code is moved to
AbstractClient and invoked from Client::enterNotifyEvent.
This includes the methods:
* decoration()
* decoration() const
* isDecorated() const
In addition new protected methods are added to destroy the Decoration
and to set it.
Usage of m_decoration in Client code is adjusted.
it seems we can "loose" focus reversions when the closing client hold a grab
(eg. the screenlocker or some games) thus we catch the typical pattern
(though we don't want the focus on the root anyway)

Properly handle the mouse press/release events in InputRedirection
while we move windows. If it's the last mouse release event we end
the move resize of the window. For that we reuse the code written
in Client.
Implementation is moved to abstract_client.cpp as so far events.cpp
does not have any code from AbstractClient.
This includes moving the electricMaximizingDelay from Client to
AbstractClient.
Workaround, this *seems* a Qt problem.
The grab fails while the button is down - Qt then also seems
to release the keyboard.
Not sending it to the deco didn't help either - nevertheless it seems
(from the Qt code) as if the button is currently grabbed
(the code is a dumb forward to xcb_grab_pointer)
As a workaround, the patch simply ensures a grab on releasing a button when
the popup is visible.

a) if the move is left after the delay is triggered
but before the timer hit, do not cause a stale QT
indication
b) only delay QT if there's actually another screen
on the other side

The user might just want to move the window from
one screen to another, no point in wasting time to
show the indicator

notably *after* storing the old values.
Otherwise the old value is polluted because of
m_hints being nullptr, thus a default value is
returned (instead of the actual old value)

We need to send a fake HoverMove event on minimized to remove all
hovered states of the decoration.
At the same time we need to ensure that no further hover events are
sent to a minimized client.

The creation of PlasmaWindowInterface is moved from WaylandServer into
AbstractClient. This allows the sub classes to better control when to
create/destroy the Client.
For creation it's bound to becoming visible - that is Windows which are
only created but never shown are not announced at all.
For Client it's destroyed with the normal tear-down of a Client, for
ShellClient it's destroyed on unmapped (which also means a new one
will be created again in case of another mapping of the surface).
As a side effect, this works around the problem that ShellClients do not
yet get destroyed for QtWayland's menus (needs further investigation).
Adds the SurfaceInterface identified by the surface id we get from
Xwayland. This allows in an easier way to map a Toplevel to a
Wayland surface and will also be useful for Wayland clients.
When XWayland associates a Wayland surface with an X window it
sends a WL_SURFACE_ID client message to the window manager.
KWin listens for this client message in Toplevel and provides it
as a member in Toplevel.
This requires KWin to actually start a Wayland server (and XWayland)
to make proper use of the information.
A wrapper class for MotifHints is added to xcbutils. This class manages
the information about the read Motif hints, so that Client doesn't need
to have a copy of the read states.
The class is designed in a way that during Client::manage we get rid of
another roundtrip.

The build option got introduced for Plasma Active back in a time
when we did not properly aim for convergence. In a Plasma 5 world
we want to have only one shell and one window manager which adjust
itself. This means we don't want a differently compiled kwin for
plasma active, but the same one. Thus the build option doesn't
make much sense any more. A KWin for touch interface needs to support
screenedges for the case that mouse is plugged in.

We are only using the UrgencyHint, InputHint and GroupLeader from
WMHints. Those are provided by NETWinInfo, so we can use the
functionality provided by NETWinInfo instead of calling XGetWMHints.

NOTE: this is not working completely yet, lots of code is still ifdefed
other parts are still broken.
The main difference for the new decoration API is that it is neither
QWidget nor QWindow based. It's just a QObject which processes input
events and has a paint method to render the decoration. This means all
the workarounds for the QWidget interception are removed. Also the paint
redirector is removed. Instead each compositor has now its own renderer
which can be optimized for the specific case. E.g. the OpenGL compositor
renders to a scratch image which gets copied into the combined texture,
the XRender compositor copies into the XPixmaps.
Input events are also changed. The events are composed into QMouseEvents
and passed through the decoration, which might accept them. If they are
not accpted we assume that it's a press on the decoration area allowing
us to resize/move the window. Input events are not completely working
yet, e.g. wheel events are not yet processed and double click on deco
is not yet working.
Overall KDecoration2 is way more stateful and KWin core needs more
adjustments for it. E.g. borders are allowed to be disabled at any time.
This is going to be a controversal change. It enforces KWin decorations
on all client side decorated windows from GTK+. Unfortunately we are
caught between a rock and a hard place. Keeping the status quo means
having broken windows and a more or less broken window manager due to
GTK+ including the shadow in the windows. This is no solution.
Enforcing server side decorations visually breaks the windows. This is
also no solution. So why do it?
It's our task to provide the best possible user experience and KWin is
a window manager which has always done great efforts to fix misbehaving
windows. One can think of the focus stealing prevention, the window rules
and lately the scripts. The best possible window management experience is
our aim. This means we cannot leave the users with the broken windows
from GTK.
The issues we noticed were reported to GTK+ about 2 months ago and we are
working on improving the situation. Unfortunately several issues are not
yet addressed and others will only be addressed in the next GTK+ release.
We are working on improving the NETWM spec (see [1]) to ensure that the
client side decorated windows are not in a broken state. This means the
enforcment is a temporary solution and will be re-evaluated with the next
GTK release. I would prefer to not have to do such a change, if some of
the bugs were fixed or GTK+ would not use client-side-decos on wms not
yet supporting those all of this would be a no issue.
For a complete list of the problems caused by GTK's decos see bug [2] and
the linked bug reports from there.
The change is done in a least inversive way in KWin. We just check for
the property _GTK_FRAME_EXTENTS and create a Q_PROPERTY in Client for it.
If we add support for the frame extents in future we would also need
this. So it's not a change just for enforcing the decoration.
The actual enforcing is done through a KWin script so users can still
disable it.
