Supported Features:
* move/resize
* active/inactive
* special window type
* window decoration as missing in AnimationEffect
The animations are cancelled when they go into an invisible state (e.g.
desktop changed, minimized) and are set again when the window becomes
visible.
Where a transition is useful, the window gets animated, e.g. start/finish
of move resize.

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.

This effect is controlled by KScreen. It fades out all windows when
KScreen requests this and gives feedback to KScreen once all windows are
faded out. This allows KScreen to adjust the screens in a flicker free
way.

Shader moved to 1.10 subdirectory and a new version for 1.40 added.
At the same time call to glPolygonMode removed as it caused errors with
core context (and seems to not be needed).

Shaders are moved into dedicated directories 1.10 and 1.40. 1.10 contains
the already existing versions, 1.40 copies of them adjusted to GLSL 1.40.

With the removal of BoxSwitch all effects which want mouse events use the
fullscreen input window. The available functionality is too complex both
in EffectsHandler and in the Effects.
With this change only fullscreen input windows are supported and all
effects share the input window. This means there is at maximum one input
window. This simplifies the code in the Effects as they don't have to
keep track of the window they created any more. In EffectsHandler it
means that only one window needs to be created, destroyed and raised.
Also it means that we can properly react on screen size changes which had
been ignored in the past. Also quite some roundtrips to X are no longer
needed as we do not need to query the window geometry when creating the
input window.

The non-composited part handles the showWithX case with the four small
windows. The composited part shows a translucent QWidget with the
FrameSvg as done by the selection effect frame.
Outline connects to the Compositor toggled signal to switch the mode if
compositing gets suspended/resumed. This works fine also in the case that
the switch happens while the outline is shown. To support this Outline
is now a QObject and created with Workspace as a parent.
Given that the Outline handles both cases by itself, the outline effect
is no longer needed and is dropped together with all the hooks into the
effect system.
The usage has always been questionable as the thumbnails are
too small to properly recognize something.
Now BoxSwitch Effect has reach its end of life which would have
required to keep most of the code just for this thumbnail bar.
If required it would be better to integrate the normal QML based
TabBox to be rendered together with an effect.
