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)

Input-method servers, like maliit, need to be known to KWin since KWin
needs to know about virtual keyboards. Virtual keyboards should be shown
as OSD layers, and they are one of the types of windows that actually
should be showable when the lock screen is active.
kwin_wayland --inputmethod /path/to/your/input-server
tries to start the input server. The input-server's window never gets
keyboard focus and is shown on top of all windows except for KWin's
internal clients.
m_unmapped determines whether the ShellClient wantsInput. This is used by
the ScriptingModel to check whether a ShellClient should be included. It
gets triggered by windowShonw signal called from setReadyFromPainting. If
m_unmapped is still true at that point the ScriptingModel doesn't include
it.
The PlasmaShell interface allows to create a PlasmaShellSurface for a
given Surface. Through this interface the Surface can request:
* a specific position
* a window type
So far only the window types Normal, Panel and Desktop are supported
which is a sufficient subset for getting plasmashell to work.
In future there should be security checks so that only the dedicated
desktop shell can bind these interfaces.
We need to set the depth in order to properly determine whether the
Surface has an alpha channel and whether blending needs to be enabled
for rendering.
For this a new method is introduced in Toplevel to set the depth. If
the depth changed in a way that the Toplevel gained or lost the alpha
channel a signal is emitted which implies that the hasAlpha property of
Toplevel is no longer constant.
Fixes regression introduced with 90a6814: we may not queue a signal
taking a pointer to a ShellClient as the ShellClient might be destroyed
before the queued signal is delivered.
The idea for the queued signal was to ensure that the size is set when
windowShown is emitted - this can also be achieved by first updating the
size.
We need a shared window id in some way to e.g. properly support TabBox.
Though I do not like that the return value is xcb_window_t. This should
be either changed or a new "generic" windowId needs to be introduced.
The internal used window Id consists of two parts identifiying the
Client and one identifying the Surface. That is the first 16 bits
are set to the ClientConnection, the last 16 bits are taken from
the Surface id. As the Surface id is 32 bits, but we only use 16 bits
there is a chance of overlap. So this might need some improvement.
If the ShellClient got created for a Qt internal window, we try to
find the QWindow and if we get one, we use the geometry directly as
it got set by KWin in the first place.
Also a windowId() is added to ShellClient which can be used by the
effect system to find an EffectWindow. If it's an internal QWindow
we just use that window id. For other clients we still need some
smart solution.
The ShellClient is a Toplevel subclass for a
KWayland::Server::ShellSurfaceInterface. It gets created when a new
ShellSurfaceInterface is created and destoryed when it gets unmapped.
So far the usage is still rather limited. The ShellClient is opened
at position (0/0). While it's possible to pass pointer events to it,
it's not yet possible to activate it, so no keyboard focus.
