Summary:
We no longer need to include xcb/xfixes.h in cursor.cpp because
X11Cursor moved to its own file.

Summary:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<- .
This brings kwin decorations in line with GTK CSD icons.
In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.
Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.
Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)
Test Plan:
Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

Summary:
A dedicated X11EventFilter is added and created from the X11Cursor in
case we have XFixes. This means some more X11 specific code is now only
on X11.
Test Plan: Only compile tested.

Summary:
There are a few places where KWin needs to read values from kcminputrc.
As I need to add yet another one it makes more sense to properly
structure it like in other cases and have only one kcminputrc hold in
the application. This also allows to better mock the config values in
the integration tests.

Summary:
So far the tracking for cursor shape was done incorrectly on Wayland by
only listening to X11 cursor changes. That's from a time when
KWin/Wayland was still run on top of an X server.
Nowadays the Platform tracks cursor shape changes and emits changes to
it. Xwayland cursor changes go through the normal Wayland way so it's
just one way to get it on Wayland.
This change adds the required connect and changes the signal signature
in Cursor by dropping the serial argument. No user of the signal uses
the argument and on Wayland we don't have a serial for the cursor. So it
can be dropped.
Test Plan: Zoom effect updates cursor shape correctly on Wayland

At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.
By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.
This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.
The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.

By default the InputRedirectionCursor is created and only the X11
standalone platform creates the X11 specific cursor.
This is a preparation step for moving the X11 specific cursor
implementation into the x11standalone platform plugin.
Summary:
With this change KWin/X11 reuses Wayland's modifier only shortcut
architecture. The XInput2 event filter also listens for
* XI_RawKeyPress
* XI_RawKeyRelease
Those events are also reported if another X11 client grabs keyboard
input. Thus KWin gets all key events, just like on Wayland.
All key events are then sent through the Xkb class which performs the
mapping from key codes to key syms and is able to detect whether the
modifier got pressed/released without another key being pressed.
This change will require a few follow up changes, which are required
also for Wayland:
* ignore if another input device got interacted (e.g. mouse press,
touch screen, scroll, etc)
* use the layout from XServer instead of using our own (needed on
Wayland in nested setup)
The biggest disadvantage of the change is that it triggers a wake
up of KWin on every key event. But as KWin already listens to all
pointer events that's not a big difference and normally a key event
will wake up the compositor any way.

Summary:
The mouse polling is also used to detect mouse button press/release
events. This is used e.g. by the MouseClickEffect. The XInput2 filter
only selected for Raw Motion events which means mouse button events
are missed in case it's not combined with a motion.
This change makes the input filter also select for raw button press
and release events. To support this the X11EventFilter needed to
be adjusted to support multiple generic event types to filter for.

Replaces the timer based polling approach. If XInput is available we
listen for the RawMotion event on the root window and use this to
trigger a mouse pointer position.

The button state was not represented correctly which was very visible
when using the MouseClickEffect. Now MouseClickEffect on Wayland works
as expected.
In kwin_wayland the InputRedirectionCursor is created before the X11
connection is established. Because of that possible usage needs to
be guarded. This is only in cursorTracking so far. The parent class
exposes whether the cursor is tracked and the doStartCursorTracking
gets invoked again when the x11Connection becomes available.
The porting to Qt5 broke the timestamp handling in many areas. A deeper
look into Qt's xcb plugin shows that the appTime handling is not
sufficient for KWin's need. E.g. the time is only updated in response to
a property notify event if it's for a Qt created window, which is hardly
ever the case in KWin. Another example is that key press/release events
never updated the appTime.
As the functionality in Qt is rather trivial we can do the timestamp
handling ourselves. We filter all events anyway and it is slightly faster
as we don't have to go through the QPA interface any more.

Straight forward port from XLib based XCursor library to the
xcb variant which is considerably new. The xcb variant only allows
to create xcb_cursor_t for the default theme and size. Which suits
the needs in Cursor quite well, but means it's not a replacement for
the usage in zoom effect.
REVIEW: 122290
So far all cursors were only resolved through Qt::CursorShape, but
Qt::CursorShape is not a complete mapping of all cursors used inside
KWin. E.g. killwindow uses the "pirate" cursor.
This change keeps the cursors by name instead of Qt::CursorShape and
thus allows us to use Cursor for resolving XCursors everywhere.
In a default startup startkde does not set XCURSOR_SIZE environment
variable. Only XCURSOR_THEME is set. The size should be DPI dependent.
With this patch Cursor is able to handle this situation and does not
fall back to loading the config from file. Logic is taken from
KHintsSettings in frameworkintegration which in turn is from
KApplication.

Used by Cursor to properly emit the mouseChanged signal which for
historic reasons includes the keyboard modifiers.
Again some fiddling around with the autotests and kcmrules needed to
make it compile. This needs improvement!
New inheriting class which uses the InputRedirection to track the cursor
position. It doesn't support warping of cursor.
This introduces a slight dependency loop in the startup. Cursor needs to
be created after the WaylandBackend to ensure that the operation mode is
set correctly. But the WaylandBackend itself is accessing Cursor. It
should be safe as inside the WaylandBackend it's only accessed after
callbacks.
required until there's a dynamic poll rate, because 10Hz is too
low for magnifiers (lag), mousemark (paints too edgy), mouseclick
(often fails because it's easy to cycle the button state within 100ms)
- and the bouncing icon lags behind the mouse as well ;-)

KWin::Cursor can track changes to the cursor image. It supports a
start/stop tracking to not handle these events if nobody is interested in
them. When enabled and the cursor image changes a signal is emitted with
the serial number of the new cursor image.
To track cursor image changes xcb_xfixes_select_cursor_input is used (see
XFixes Version 5.0 protocol, section 7).
This could be useful for the zoom effect when it replaces the cursor.

The define KWIN_SINGLETON adds to a class definition:
public:
static Foo *create(QObject *parent = 0);
static Foo *self() { return s_self; }
protected:
explicit Foo(QObject *parent = 0);
private:
static Foo *s_self;
There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.
The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:
Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
Q_ASSERT(!s_self);
s_self = new Foo(parent);
return s_self;
}
In addition there are defines to again set a different variable name and
to create an object of another inheriting class.
All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.
REVIEW: 109865
With Qt5 QCursor does no longer provide ::handle() which was used to
set a cursor on a native XWindow for which we do not have a QWidget.
Also KWin has had for quite some time an optimized version to get the
cursor position without doing XQueryPointer each time ::pos() is called.
These two features are merged into a new class Cursor providing more or
less the same API as QCursor.
In addition the new class provides a facility to perform mouse polling
replacing the implementations in Compositor and ScreenEdges.
For more information about the new class see the documentation for the
new class in cursor.h.
