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.
We don't need to queue the method invokation any more to ensure the
Wayland server connection is flushed since we have the dispatch method
in waylandServer().
So far input events were sent through Xwayland which is not needed as
we have all information available. Even more it had the pointer surface
on the wrong window when interacting with decorations as it was on the
window and not on the decoration.
We need XCB 1.10 for sync to work. Sync was optional with a version check
to make it work on build.kde.org. The CI system supports XCB 1.10 now, so
it's better to have it as a mandatory requirement.
When switching virtual terminals,
suspending to ram and resizing the
screen (GL viewport) at least the
nvidia driver moves VBO data between
the video RAM and the system heap -
and something about this isn't reliable:
An often perceived resulted are scattered
windows but it may also be the cause for
entirely black screens reported for same
occasions.
As a workaround, we hook into the GL debug
messages and filter them for the suspicious
message, then re-init VBOs

figure whether that's our fault or nvidias
