Currently, if the screen edge is blocked and the cursor is inside its
approach geometry, kwin is going to paint screen edge glow.
It doesn't look good and it can have some performance penalties with
fullscreen video games because the direct scanout path will be blocked.

At the moment, dmabuf importing is scattered all over the place in kwin.
It would be great if we had one function that takes dma-buf attributes
and returns an EGLImage if successful.
As the first step, make linux-dmabuf-v1 implementation provide dmabuf
attrs compatible with KWin::DmaBufAttributes.
QSize() will construct an invalid size. An invalid size has width and
height set to -1. In other words, QSize() != QSize(0, 0). This can create
issues when computing the bounding rect of a surface that has invisible
subsurfaces.
For example, if the subsurface rect is QRect(0,0 -1x-1), the top-left
corner of the bounding rect will be affected.
In order to make computation of the bounding rect robust, initialize the
surface size to 0 explicitly.

Originally, DeformEffect was meant to be used in effect that deform
windows, but its usage has become wider than anticipated. This change
renames the DeformEffect to OffscreenEffect to accommodate for that.
In Gtk's text-input-v3 implementation it expect done to update the
client serial after every commit. Though it is unclear whether this is a
protocol requirements, do the same thing like mutter for more
compatiblity, especially Gtk3 is in EOL not likely to be patched any
time soon.
To do so, we will need to keep track of the last active preedit,
otherwise only send_done() will clear the preedit.
Behaviour was fixed in c3f5f8ce01. If an
item starts at 0,0 and is 100 pixels wide in normal geometry the 100th
pixel is not inside the rectangle.
SubSurface::testSurfaceAt was adjusted correctly but this was missed as
we test the same thing twice!
QRectF::contains includes all edges. If two subsurfaces are next to each
other ::contains will treat it as having a singularity where a value is
on 2 subsurfaces rather than either one of the other, which isn't what
we want for our purposes.
The unit test is extended but also featured some wrong values, the
biggest clue that it was wrong was that we used different test
co-ordiantes for surfaceContains and inputContains.
Anything in xcb_ structs are always in X local, all member variables
aside from buffers are in kwin local space.
This patch ignores a few paths that are not relevant on wayland.
This allows for compositor managed different co-ordinate space between kwin's
logical co-ordinate space and a client's logical co-ordinate space.
When combined with a modified kwin!1959 this allows us to set a DPI in xrdb and
mark all xwayland windows as being 2x (or other) and avoid upscales for xwayland
clients in a way that doesn't impact other wayland clients or require
third-party changes. Any use of fractional values is in layers we control
instead of over the wire. kwayland-server is the right place for this
abstraction as we need Outputs to differ on a per resource basis. Something we
can't control from within kwin.
Right now only protocols used by Xwayland are covered. If we covered
remaining protocols we can offer user-control on all remaining clients which
could open up other possibilities such as a user controlled dynamic resizing,
or adapt to possible future protocol changes with wayland scaling.
Allow dragging windows between screens, using a placeholder thumbnail item to
render part of the thumbnail on the other screen.

There are a few benefits to using smart pointers from the standard library:
- std::unique_ptr has move semantics. With move semantics, transfer of ownership
can be properly expressed
- std::shared_ptr is more efficient than QSharedPointer
- more developers are used to them, making contributions for newcomers easier
We're also already using a mix of both; because Qt shared pointers provide
no benefits, porting to standard smart pointers improves consistency in
the code base. Because of that, this commit ports most of the uses of QSharedPointer
to std::shared_ptr, and some uses of QScopedPointer to std::unique_ptr
The current shortcuts could conceivably override app shortcuts, since
they don't use the Meta key. The following changes are made:
Switch keyboard layout: Ctrl+Alt+K -> Meta+Alt+K
Activate window that wants attention: Ctrl+Alt+A -> Meta+Ctrl+A
Kill Window: Ctrl+Alt+Esc -> Meta+Ctrl+Esc
These are safe to change in the code rather than adding new ones and
keeping the old ones around for compatibility's sake because
KGlobalAccel::setDefaultShortcuts by default preserves old shortcuts
when they are changed, and we aren't overriding that behavior here. So
only new installs will get the new shortcuts and existing user installs
will be untouched.
Makes sure disabled outputs are reported as such, leaving behind the
assumption that all outputs are always enabled.
Ensures the corresponding outputEnabled/Disabled signals are emitted.
Updates the window title to reflect the output state.
AppletPopup window type should accept focus, behaving like other window types like
Dock. At the moment it is instead behaving like notification, which seems wrong.
This should also fix a failing unit test.
AppletPopup's are typically supposed to be attached to the panel and
should remain visible when the virtual desktop is changed. If the
AppletPopup is pinned and the virtual desktop is changed, without
this patch, the window does not remain attached to the panel. This is
how AppletPopup was supposed to work even according to the unit test
which currently fails.
The lowest latency setting wasn't applied because the internal
implementation contained an excess 'e' in comparison to the setting
exposed to the user
