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.

Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
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 main usage of ShaderManager::isValid was to have OpenGL2 specific
code pathes. Now we have an actual OpenGL2Compositing type and we know
that the ShaderManager is valid if we have this compositing type and we
know that it is not valid on OpenGL1Compositing. This gives us a much
better check and allows us to use the isValid method just for where we
want to check whether the shaders compiled successfully.
In addition some effects require OpenGL2, so we do not need to check
again that the ShaderManager is valid. Such usages are removed.
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 supportInformation is extended to also read the properties
on all effects. In addition each effect can be queried just for
itself through D-Bus, e.g.:
qdbus org.kde.kwin /KWin supportInformationForEffect kwin4_effect_blur
All effects are extended to provide their configured and read
settings through properties. In some cases also important
runtime information is exposed.
