c7262e8bd3 Getter/setters for opacity, saturation and brightness in WindowPaintData 
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.

This commit is the top-most of a patch series to refactor
ScreenPaintData and WindowPaintData. Other related commits are:

a79eacaed7 Properly detect effects which need OpenGL 2 
Effects that need GLSL require that OpenGL 2 is active.
It does not matter whether the GPU would support it if
OpenGL 2 is not used.

07685da24e Check whether the ShaderManager is valid in Explosion effect 
The effect did not check whether the ShaderManager is valid causing
a null pointer access when trying to use the shader.

Additionally this change moves the Shader init into the close window
slot as close window referrenced windows without checking whether the
effect would work. If the effect would not work each closed window
would be referrenced without any chance to being unreffed again as this
code is in a block checking whether the effect is valid.

fe4329a252 Only call active effects in the effect chain 
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.

0b85768ec5 EffectsHandler emits windowClosed signal 
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.

0f7ebac00e Explosion portet to GLES. 
I'm not completely sure if this is how the effect should look like.
But I cannot verify, it fails on fglrx and cannot find a video on Youtube.

846496d2c1 Cleaned up the effects/ directory by moving each individual effect into 
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
