One resource is used for shader version 1.10 and one for version 1.40.
The ideas behind this change is to remove the locating of the shader
sources and also to fix that user provided shaders could be loaded
instead of the original ones (possible attack vector on Wayland).
To simplify the ShaderManager provides a new method call to load the
shader from the resource. This means the effects don't need to
duplicate the check for the shader version any more and also don't
need to duplicate the file reading functionality.

This method replaces the X-KDE-ORDERING property in the Effect's desktop
files. This change is a preparation step for integrating the new Effect
Loader which doesn't read the ordering information. Thus it needs to be
provided by the Effect itself so that the EffectsHandler can properly
insert it into the chain.
Also for the built-in Effects on the long run it doesn't make much sense
to install the desktop files. And binary plugin effects will migrate to
json metadata which also doesn't have the KService::Ptr. Thus overall it
simplifies to read this information directly from the Effect.
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 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.

Cube effect loads 0 to 2 textures which has been
performed during configuration. This change delays
loading the textures till cube is activated for the
first time and the loading from file is moved into
a thread.
This means that for a very short time the texture
is not yet visible, but this is not a problem as
the cube animates from fully opaque starting state.
So during the loading the texture would not be
visible anyway.

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.
Rotation is now only handled by the QMatrix4x4 m_rotationMatrix,
so no more need for display lists. Resulting in a cleaner code without
differences between OpenGL 1.x and 2.x/GLES.
This includes quite some refactoring. For the cube cap a VBO is used
instead of glLists and all the required transformations are moved into
paintCap() which makes paintScreen more clean.
Currently the mirroring of bottom texture is still missing and cylinder
and sphere caps are not yet ported to using VBO.
I wouldn't be surprised if it is broken for legacy GL atm.
Currently working:
* cube slide
* basic cube
* rotations
* reflections
Not working:
* Cube Inside effects
* Reflection plane (needs to be done in a shader)
* cube caps
* sphere/cylinder
* filled in areas in multi desktop
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.

There are two small todos: when mixing manual (mouse) rotation with cursor key rotation or zooming the reflection becomes wrong.

* it looks strange
* it changes the projection matrix which makes the code ugly
* it never worked with cylinder or sphere
* it was broken in trunk anyway

Plasma frame object. There are two ways to use this class: The first is
in "static" mode which gives the frame a set geometry and will not
change, the second is an automatic mode that creates the smallest
possible frame around the specified contents. Contents can either be
normal text and/or a QPixmap, useful for displaying the caption and icon
of the currently highlighed window.
Known bugs:
- Does not detect Plasma theme changes, known to be in the Plasma
library.
- Slight graphical glitches, known to be in Qt 4.5.0 RC1.
Untested:
- What happens when there is no Plasma theme installed.

* Code restructuring and clean-up
* Use of glLists to store the rotation and painting of the cube. That way things are only calculated when something changed. Painting the cube is still required in each frame as it would break all other effects.
* Use face culling to paint the cube in the correct sequence.
* Move loading of all settings to cube effect. In preparation of getting rid of cylinder and sphere classes
Known regression: cylinder and sphere caps are partly broken.
