Summary:
Effects that prefer to manipulate direction of animations sometimes need
to create animations in some particular state so later on they can be
played backward (swapping from and to is not enough and it would be wrong).
The proposed complete function lets such effects to fast-forward animations to
to the target position so they can be played backwards later on.

Summary:
Consider current implementation of the Squash effect: if a window was
minimized, an animation will be started; if the window is unminimized
and the animation is still active (that can happen when user clicks on
app's icon really fast), the animation will be stopped and a new one will
be created. Such behavior can lead to rapid jumps in the observed
"animation".
A better approach would be first try to **reverse** the already active
animation, and if that attempt wasn't successful, start a new animation.
This patch introduces a new function to the scripted effects API that
lets JavaScript effects to control direction of animations. The
prototype of the function looks as follows:
redirect(<animation id(s)>, <direction>, [<termination policy>])
the first argument is an animation id or a list of animation ids, the
second argument specifies the new direction of the animation or
animations if a list of ids was passed as the first argument. The
third argument specifies whether the animation(s) should be terminated
when it(they) reaches the source position, currently it's relevant only
for animations that are created with set() function. The termination
policy argument is optional, by default it's Effect.TerminateAtSource.
We can use this function to fix issues with rapid jumps in the Squash
effect. Also, redirect() lets us to write effects for simple animations
in slightly different style: first, we have to start the main animation
(e.g. for the Dialog Parent effect, it would be dimming of main windows)
and then change direction of the animation depending on external events,
e.g. when the Desktop Cube effect is activated.

If the cross fade animation is cancelled, we are not gracefully
unreference the previous window pixmap.
This change addresses that issue by using RAII approach to
reference/unreference the previous window pixmap.
Test Plan: Manually. The Maximize and the Morphing Popups effect still work.

Summary:
862bf0f153 introduced a regression(sorry
for that): if you close a confirmation dialog(with the Scale effect and the
Dialog Parent effect being enabled), the main window(s) will flicker.
That flickering happens because the C++ version of the Scale effect and
AnimationEffect unref deleted windows in different places. AnimationEffect
unrefs deleted windows in prePaintScreen, which btw is not the best
place to do that. The C++ version unrefed windows in postPaintScreen.
So, when the Scale effect has finished animating the main windows, it
will unref them, but windowDeleted signal won't be emitted immediately.
Which means that the Dialog Parent won't be able to delete corresponding
animations on its side and main windows will be painted for a single
frame.
This change addresses flickering by adjusting prePaintWindow in
AnimationEffect so deleted windows won't be painted if none of
animations keeps them alive.
Test Plan:
(make sure that both the scale and the dialog parent effect are enabled)
* Go to System Settings > Application Style > Window Decorations;
* Select a decoration that is different from the current;
* Close the system settings window (don't click "Apply" button);
* When a dialog is shown, click "Discard" or "Apply" button.

Summary:
If a modal window is closed and some alternative effect that animates
the disappearing of windows is enabled(e.g. the Glide effect, or the
Scale effect), the Dialog Parent effect can cause flickering of the
parent window because its animation duration doesn't match duration of
those alternative effects.
Also, if the Fade effect, the Glide effect, and the Scale effect are
disabled, the Dialog Parent will keep the parent window alive for no
good reason.
This change addresses that problem by adding keepAlive property to
`animate` function so scripted effects have more control over lifetime
of animated windows.
If both a modal window and its parent window are closed at the same time
(and there is no effect that animates the disappearing of windows), the
Dialog Parent will stop immediately(because windowDeleted will be
emitted right after windowClosed signal).
If both a modal window and its parent window are closed at the same time
(and there is effect that animates the disappearing of windows), the
Dialog Parent won't reference the latter window. Thus, it won't cause
flickering. I.e. it will "passively" animate parent windows.

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.

using stack adresses makes it possible (even tough not frequent)
for two animations (onle just killed, one just created) to have
the same id, causing scripts to be potentially really confused.
this replaces the id with a global counter, and the
"flying tooltips" bug is gone.

Instead of getting size from displayWidth() and displayHeight() use
the information we have from Screens. This means there is only one
place to have the information and by that we can ensure that all
components use the same data to rely on. displayWidth/displayHeight
seem to provide the wrong information when unplugging an output
without disabling the output. This results in rendering artefacts.
But KWin::Screens has the correct information available.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
it seems an animation can be triggered and the resp.
window deleted in the first event cycle (before the deleted
signal is bound) - so we add an initialization flag to ensure
the binding happens before the first animation is added

Just like Opacity for transforming only the decoration opacity.
It's an ABI break as the new enum value had to be included as anonther
non-float base value.
Cross fading with previous pixmap is achieved by referencing the old
window pixmap. WindowPaintData has a cross-fade-factor which interpolates
between 0.0 (completely old pixmap) to 1.0 (completely new pixmap).
If a cross fading factor is set and a previous pixmap is valid this one
is rendered on top of the current pixmap with opacity adjusted. This
results in a smoother fading.
To simplify the setup the AnimationEffect is extended and also takes care
about correctly (un)referencing the previous window pixmap. The maximize
effect is adjusted to make use of this new capabilities.
Unfortunately this setup has a huge problem with the case that the window
decoration gets smaller (e.g. from normal to maximized state). In this
situation it can happen that the old window is rendered with parts outside
the content resulting in video garbage being shown. To prevent this a set
of new WindowQuads is generated with normalized texture coordinates in
the safe area which contains real content.
For OpenGL2Window a PreviousContentLeaf is added which is only set up in
case the crass fading factor is set.

Do not schedule repaints in AnimationEffect if there are no animations
going on. If an animation is waiting for starting or kept after ending
the visual appearance is no longer changed, so no repaint is needed.

The public member variables for opacity, saturation and brightness
are removed in favor for getter and setters. The variables are
moved into a private class. Those are now qreal instead of double.
To make usage inside the effects easier a multiply method is added
which multiplies the current value with passed in factor and returns
the new value in a functional programming style.
