1. if a client has oversize, ensure to keep the titlebar in
sight
2. if a maximized client *almost* covers the entire maximization
area, users can easily be trapped to click into the missing
pixels, thus the client below.
Therfore the clients is then stuffed into one corner, with
preference to the titlebar edge and the screen area (ie.
*away* from panels and towards actual screen borders because
of fitt's law)

Prime target is to preserve the in-screen
condition of client AND window.i[1]
Atm. when the client is fully in sight
(but the window is not) - regardless of snapping
or screen change - a workspace update (screen change,
resolution change, adding/removing a strutting panel)
would allow the client to partiall escape screen bounds.
This is changed so that if the client is fully in sight,
it's kept fully in sight (but not the decoration)
If the entire window was fully in sight, it's also kept
(as is right now)
The code handles inner screen edges (if the client was in sight,
the entire window will be if we'd bleed to the other screen)
[1] I'd say that handling the client is more relevant,
but foresee more complaints if the window wasn't handled anymore ;-)
During that, i stumbled across some other issues.
- when a window centered on one screen is moved to a screen smaller
than the window, the window is shrinked to the dimensions of that
screen and now randomly touches eg. left AND right edge. When
moved back, the right and bottom edge were preferred
(to the window was "moved" into the lower right corner).
It's now kept centered.
- geom_restore was saved before keeping the window in the new
screen area (causing accidental drops on screen changes)

since the client is currently empty, we'll resort
to client hints, ie. effectively resize windows
when shading them (setGeometry and plainResize have
extra checks on whether this geometry is only the decoration
height to not smear client_size)

A ShellClient can have window type dock. In that case it's considered to
have a strut. That is currently every panel restricts the area. On the
other hand only internal clients can be docks at the moment. For Plasma's
panels a dedicated interface will be needed.
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.

Xcb::GeometryHints is a convenient wrapper around the size hints
as described in ICCCM combined with the sanity checks so far applied
by KWin after reading the property.
Instead of accessing the members of the property structure, we are
now using the convenience methods.
During ::manage no further actions are triggered when reading the
size hints. Only when they are read later on the previous checks
are applied. During ::manage they can be ignored as it had a dedicated
isManaged check.
The method ::resizeWithCheck got a new argument of type xcb_gravity_t
which defaults to 0. This is needed from ::configureRequest which so
far temporarily changed the xSizeHints structure. By passing as an
argument this is no longer needed.

The geometry of the window when entering QTM is
a technical detail (caused by the maximizing action
of moving the window to the upper edge) and thus
does not qualify as geometry the window should be
restored to (using a deoc button, shortcut etc.)
Mostly a safety check, but fixes a crash with borderless maximized
windows. If that option is set we also do not notify the decoration
at all, as the deco will be destroyed anyway.

checkWorkspacePosition() operates on geom_restore
to preserve window positions on temporary
(without moving/resizing the window by the user)
screen layout/geometry changes.
Therefore, in the multiscreen case the
screenbound check must be done towards
the screen the window *would* be on
according to geom_restore, not the one
it is right now.

It used to get the individual screen geometries from QDesktopWidget.
We don't need to go through QDesktopWidget any more as Screens
contains all the information we need in a more reliable way.
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.

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.
and copy isSpecialWindow() check as rulebook input
to setFullscreen()
Client::isFullScreenable() checks:
* fullscreen rule
* fullscreen_hack (-> for normal windows)
* geometry restrictions
* special window
Client::manage() for fullscreeining checks:
* fullscreen rule (with correct "initial" parameter)
* fullscreen_hack
-> this breaks the fullscreen rule for geometry restricted windows
and causes inconsistent behavior between client requests at runtime
(which do not test ::isFullScreenable()) and on mapping.
Otoh, the specialWindow() protection should apply generally - those
kind of windows should not be fullscreened since the user can not
exit this state via kwin for them - and there's hardly a good reason
for them to be fullscreen, esp. not to enter that state at runtime
