So far this only allows to trigger show desktop functionality and exports
the state.
In future this should be restricted to just one dedicated desktop shell
process.
We used to change it only on keypresses. This resulted in the strange
situation that e.g. the input method virtual keyboard doesn't show up
until one presses a real key, because e.g. maliit only activates the
keyboard if there is an active focus object in the Qt application.
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.
When we don't use the buffer anymore, we should discard it. Otherwise
we start to leak buffers and that can result in clients dead locking
while waiting for more free buffers.
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.
If the user has only maximized windows or all
windows crammed into one region of the screen
the effect would not resemble an aperture at all
this ensures a maximum amount of corners is used
while seeking to still use shortest paths

a) calculateGravitation on the same borders forth and back is idempotent
b) do not checkWorkspacePosition for shaded windows
may falsely constrain the unshaded geometry into screen bounds

BUG: 348064
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)

BUG: 348064
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.
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.
At the same time the functionality for the "original_skip_taskbar" is
splitted out. This removes the weird API with two boolean arguments to
the set method. Instead there is a dedicated method for the orignal
skip taskbar state which delegates to regular skipTaksbar.
If there is a visible internal window it gets the pointer events.
The assumption is that the last created internal window is the top
most in stacking order.
