The main difference is that the activation of an edge is no longer
broadcasted to all effects and scripts, but instead a passed in slot of
the Effect/Script is invoked.
For this the EffectsHandler API is changed to take the Effect as an
argument to (un)reserveElectricBorder. As callback slot the existing
borderActivated is used.
In addition the ScreenEdge monitors the object for beeing destroyed and
unregisters the the edge automatically. This removes the need from the
Effect to call unregister in the dtor.

This method can be used to get the animationTime in case a configuration
class generated through KConfigXT is used. In general the configuration
stores the magic value 0 for a property "duration". This magic value
indicates that a hard-coded default value should be used.
So the common logic to test the stored value for 0 and then either pass
the stored value or the default value to animationTime is encapsulated
in this method in a generic way.
A MyEffect can use it in the following way:
animationTime<MyEffectConfig>(200);

If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.
This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.
With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.
E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);
while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.
The ShaderBinder class can be used for the case that a block of code
should be executed with a given Shader being bound. This is useful for
all the cases where there is a if-block for OpenGL2 execution with a
Shader being pushed in the first line to the ShaderManager and popped in
the last line of the block. With the helper this can be simplified to:
ShaderBinder binder(myCustomShader);
or
ShaderBinder binder(ShaderManager::GenericShader);
The ctor of ShaderBinder pushes the given Shader to the stack and once
the helper goes out of scope it will be popped again from the stack.
In addition the helper can take care of OpenGL 1 compositing, that is it
just does nothing. So it can also be used where there is a shared OpenGL1
and OpenGL2 code path where the Shader should only be pushed in OpenGL2.
This basically removes all the checks for the compositing type before
pushing/popping a Shader to the stack.

The CompositingType enum turns into flags and two new values are
introduced: OpenGL1Compositing and OpenGL2Compositing.
Those new values are or-ed to OpenGLCompositing so that a simple check
for the flag OpenGLCompositing works in case of one of those two new
values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.
The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.
The code assumed that screens border to each other. That is the height
of the one screen is the y position of the other screen.

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.

Creating an EffectFrame requires I/O which takes on my system
during testing between 10 and 40 msec. Also it needs a little
bit of memory.
This changes moves out the creation of EffectFrames at Effect
load till the Effect actually needs the EffectFrame. E.g. if a
user does not filter in PresentWindows there is no need to ever
create it.
BoxSwitch effect is ignored as it should be dropped for 4.9.

For the normal TabBox the TabBoxClient's icon method is
adjusted to use the "user-desktop" icon instead of the

For the effects a method to set the caption is extended
to also set the icon on the caption frame.

Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
EffectsHandlerImpl just forwards the signals from TabBox. In order
to have a valid pointer to the TabBox, the TabBox is now initialized
before compositing in Workspace.
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
into KWin's global namespace. Morever None already kind of clashes with X's None.

Rendering of the EffectFrame is moved into the scene as Scene::EffectFrame with a concrete implementation in SceneXrender and SceneOpenGL.
A factory method for an EffectFrame is added to the EffectsHandler, which is used by the effects.
Next step: pass the EffectFrame through all effects, so that effects can transform, blur, invert whatever it.
