f521d4bbe1 [wayland] add enter/leave virtual desktop API
Summary:
As setDesktop was changed to "move" this left unSetDesktop non-symetric.

This replaces it with explicit API to enter/leave.

This also moves new API to the new object based API rather than still
using ints.

Where numbers are used it has been tidied up so that desktop IDs are
uint, which should be used when we have a list of desktops.
int is used only when we have either a desktop ID or NET::OnAllDesktops
(-1)

Effects API cleared up to use this and use a set of x11 IDs, which
avoids any potential complications of handling add and removes any
ambiguity with what happens if you leave all desktops and such.

Test Plan:
testVirtualDesktops passes (with pending kwayland patch)
Moving a window in the desktop grid on X11 behaves
Moving a window in the desktop grid on wayland behaves

99b33e7428 [libkwineffects] Expose getting/setting activeFullScript to scripted effects
Summary:
Getter is exposed as a property on scripted effect in a way that hides
pointers from the scripting side.

Setter is implicitly handled as a property of newly created animations
and holds the activeFullScreenEffect whilst any of them are active. Like
existing effects it remains up to the effect author to avoid the
problems of multiple full screen effects. The RAII lock pattern is
somewhat overkill currently, but it's the direction I hope we can take
EffectsHandler in next API break.

BUG: 396790

7ef8409157 Move X11-only specific part of EffectsHandlerImpl to x11 platform plugin
Summary:
The Platform API is extended by a call to create the EffectsHandler. In
X11 standalone Platform a new EffectsHandlerImplX11 is added which
contains the X11 only parts of the EffectsHandler, such as grabbing the
X keyboard and the X11 mouse interception window.

The EffectsHandlerImpl gains some virtual methods for the parts which
are now done in the X11 specific implementation. In return we get rid of
lots of if-else structures checking for the operation mode.

Test Plan: Only compile tested.

f7d6e4affd [tabbox] Drop the passing to Effects in X11 Filter
Summary:
If an Effect has replaced the TabBox and wants to react on mouse events
the EffectsHandlerImpl also has an X11Filter, so we only need to make
sure the events go to that filter.

Motion: TabBox did not filter out, so events will go to the Effects
filter.
Press/Release: TabBox should not operate if Effects take the events.
The events are filtered out by Effects if there is a grab, so just
check for that and go out. Effects will take care.

Test Plan: Compiles

0ed609590b Add a dedicated X11EventFilter for forwarding property events to the effect system
Summary:
So far both Workspace and Toplevel emitted signals for every property
notify event on the root window and the respective Toplevel windows. The
signals were only used in EffectsHandlerImpl to forward to the effect
system in case the property which changed is registered by an effect.

This change introduces a dedicated event filter for this which is only
created in EffectsHandlerImpl in case an X11 connection is available. It
supports a restart of the X11 system.

The signals used so far are removed from Workspace and Toplevel.

0c6fdeef2d Split out the X11 mouse event filtering for EffectsHandlerImpl
Summary:
This change introduces a dedicated X11EventFilter for the mouse
interception on X11. The filter gets created together with the start
of mouse interception and destroyed again when the mouse interception
ends. Thus we don't need to check for each event like it was the case
so far.

Unfortunately the existing methods cannot be removed (yet) as they are
still used by TabBox. Needs investigation whether this is actually
needed.

054d923411 Move SceneXRender into a plugin
Summary:
First step for loading the compositor Scenes through plugins. The general
idea is that we currently needlessly pull in all the Scenes although only
one will be used.

E.g. on X11 we pull in QPainter, although they are not compatible. On
Wayland we pull in XRender although they are not compatible.

Furthermore our current Scene creation strategy is not really fault
tolerant and can create situations where we don't get a compositor. E.g
on fbdev backend the default settings won't work as it does not support
OpenGL.

Long term I want to tackle those conceptional problems together:
we try to load all plugins supported by the current platform till we have
a scene which works. Thus on Wayland we don't end up in a situation where
we don't have a working compositor because the configuration is bad.

To make this possible the switch statement in the Scene needs to go and
needs to be replaced by a for loop iterating over all the available
scenes on the platform. If we go there it makes sense to replace it
directly with a plugin based approach.

So this is a change which tackles the problem by first introducing the
plugin loading. The xrender based scene (as it's the most simple one)
is moved into a plugin. It is first tried to find a scene plugin and only
if there is none the existing code is used.

Test Plan: Tested all scenes

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 integration tests.

2132b1e0c8 [effects] Use arg="true" in the kcfg files
Summary:
By changing all kcfg to have arg="true" we can pass in the same
KSharedConfigPtr into all effects. This allows to have fake config in
the tests and in the planned effect demo mode.

Also it means that we don't have to hardcode the name kwinrc into the
files. In the configs - where we cannot access the effectshandler - we
use the define KWIN_CONFIG which gets generated based on the compile
time arguments.

22c91df2ec Add support for global touchpad swipe gestures
Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
 * swipe up: Desktop Grid
 * swipe down: Present Windows
 * swipe left: previous virtual desktop
 * swipe right: next virtual desktop

The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.

The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.

The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
 * started: when the Gesture gets considered for a sequence
 * cancelled: the Gesture no longer matches the sequence
 * triggered: the sequence ended and the Gesture still matches

The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

f9f7b84cb4 Add interactive position selection to screenshot screen under cursor
Summary:
A second interactive selection mode gets added to select a position on
the screen. This is handled by the same input event filter as for the
window selection. Just that instead of returning a window, it returns a
QPoint.

This allows to pick a point on the screen which we need to screenshot
the screen under the mouse cursor and in future for color picking.

The screenshot effect provides two new dbus methods to (interactively)
select a screen or fullscreen. This allows spectacle to screenshot the
(full) screen with still having the user in control.

bedc01b108 [kwineffects] Add hide/show cursor to EffectsHandler
Summary:
The implementation delegates to the Platform to perform the actual
show/hide of the cursor image.

This replaces the implementation in the zoom effect which so far
directly interacted with xfixes to show/hide the cursor. This is now
provided by the x11/standalone platform. And due to this change the zoom
effect can now properly hide the cursor on platform DRM (wayland) as
well.

ea52ef9e57 Add a PlatformCursorImage to Platform and EffectsHandler
Summary:
There are several effects (screenshot, zoom) which need access to the
cursor image and cursor hotspot. So far these effects used X11
unconditionally to get the cursor which obviously does not work on
Wayland.

This change adds a new class PlatformCursorImage to kwinglobals which
wraps what a cursor is (image and hotspot) and adds a new virtual method
to Platform to provide such a PlatformCursorImage. By default it's the
cursor image the Platform tracks. On X11/standalone platform this new
virtual method is overriden and provides a PlatformCursorImage from X11
using the code previously used in screenshot effect.

Screenshot effect and zoom are adjusted to use the new API instead of
X11.

Test Plan:
Zoom effect tested on Wayland, now gets the proper cursor icon.
X11 functionality not yet tested.

2545162f87 Support highlighting windows through EffectsHandlerImpl
Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.

This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.

The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.

Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

6af0cc6ebe Add support for touch events in the Effect system
Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp

The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.

This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.

As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.

142aab2e24 Introduce an EffectsHandler::animationsSupported -> bool
Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.

This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.

As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.

The information whether animations are supported comes from the Scene.
It's implemented in the following way:
 * XRender: animations are always supported
 * QPainter: animations are never supported
 * OpenGL: animations are supported, except for software emulation

In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.

a029300ce5 Rework cursor image handling for Wayland
So far updating the cursor image was not really defined. It was possible
to use the cursor image from the wayland seat or have a custom set cursor
image. But there are no rules in place to decide which one to use when.

With this change a dedicated CursorImage class is introduced which tracks
the cursor image changes on the seat, on the decoration, in the effects
and so on. In addition it tracks which is the current source for the
image, that is whether e.g. the cursor from the seat or from effects
override should be used. Whenever the cursor image changes a signal is
emitted, which is connected to the signal in AbstractBackend.

Based on that the backends can directly show the image. The existing
code in the backends to install a cursor shape or to install the cursor
from the server is completely dropped. For the backend it's irrelevant
from where the image comes from.

A new feature added is that the cursor image is marked as rendered. This
is then passed on to the frame rendered in the Surface and thus animated
cursors are finally working. Unfortunately animated cursors are broken in
Qt (see https://bugreports.qt.io/browse/QTBUG-48181 ).

b57885a1bf Add registerGlobalShortcut method to kwineffects
Implemented in KWin core to forward to new global shortcut system. This
method should be extended/changed once we go to Qt5/KF5 to make the usage
easier (no more KAction).

Each global shortcut in the effects makes use of this new method.

6619faa6ac Pass pointer events through the effect system
InputRedirection forwards pointer events (currently motion, press and
release) through the EffectsHandlerImpl for the case that an effect has
intercepted pointer events.

If the KWin operation mode is not X11 only, the window for intercepting
the mouse events is no longer created.

e3271ec2e1 [kwin] Add isEffectSupported method to Effects DBus interface
EffectsHandlerImpl::isEffectsSupported performs the check whether the
effect with the given name is supported by the current compositor.

The check is the following:
* if effect is already loaded, it is supported
* if the effect cannot be found, it is not supported
* if it's a scripted effect, it's always supported
* if it's a built-in effect, we ask BuiltInEffects::supported
* for all other effects we resolve the library and the supported
  method

The idea behind providing this functionality in the DBus interface is
to allow filtering in the effects KCM for the effects which are
supported by the current compositor.

In addition a areEffectsSupported method is added which takes a
list of names and returns a list of bools.

6b1f0b1fca [kwin] Introduce Screens::size and Screens::geometry
Screens provides a size which is constructed from the size of
the bounding geometry of all screens and provides an overload taking
an int to return the size of a specified screen. For geometry() a new
ovload is added without an argument, which is just a convenient wrapper
for QRect(QPoint(0, 0), size()).

Both new methods are exported to effects and scripting as new
properties there called virtualScreenSize and virtualScreenGeometry.

The (virtual) size gets cached in screens and is updated whenever the
count or geometry changes.

Construction of Screens is slightly changed by moving the init code
from ctor into a virtual method init(). Reason is that we ended in
a loop with accessing the singleton pointer before it was set.
