Scale window contents and decorations togheter in order to
avoid 1px glitches caused by rounding errors;
This has the net benefit of scaling only one pixmap instead of two
for each window*clipper and should actually give some performance bonus
I've tested this for some time with no issues, but this commit
*might* cause regressions. In case, let me know.

The code controlling timing for the animations
assumes that all painting is finished when the
Scene has finished painting. Since the X protocol
is asyncronous we need to call XSync (and not XFlush)
to make sure all painting has finished.
Tested for more than 2 weeks without issues.
NB: This is the same commit as

due to style changes in kwin code I could not cherry-pick
it cleanly
differecens to patch atteched to 258971:
- removed debug statements
- fixed indention...
- NON vsync strategy does not rely on the estimation, but on the time passed since the last repaint trigger, allowing a precise framerate

This allows an effect to fade between old and new text/icon. As an example it's added to CoverSwitch.
Currently only supported in OpenGL. XRender might be added, but I'm missing an idea for an effect to add it.
Most effects using EffectFrame require OpenGL anyway.

So it is more consistent (in KDE newspeak "elegant") with other selections and as a plus we get rid of all the custom rendering code in boxswitch.

Some effects (boxswitch and flipswitch) still need to be changed to not set the icon in each frame.

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.

Currently selfcheck causes bad flicker (due to X mapping the overlay window
for too long?) which looks bad during KDE startup. With this patch, KDE startup
is without any flicker.

Also slightly redo the #define's for effects, now it's:
- #ifdef KWIN_HAVE_COMPOSITING to check whether there's any compositing support at all
- #ifdef KWIN_HAVE_OPENGL_COMPOSITING to check for OpenGL-based compositing
- #ifdef KWIN_HAVE_XRENDER_COMPOSITING the same for XRender

The 'ignore ARGB visuals' option from Kompmgr probably doesn't make
much sense, those (usually old) apps can be run with XLIB_SKIP_ARGB_VISUALS=1 set.
Also remove the alpha clear hack used for decorations - I think decorations
instead should be fixed not to "unintentionally" have alpha set.

for use in effects (and not only). Now a list of window quads (=window areas)
is created at the beginning of the paint pass, prepaint calls can modify
the split itself (i.e. divide it into more parts). The actual paint calls
can then modify these quads (i.e. transform their geometry). This will allow
better control of how the split is done and also allow painting e.g. only
the decoration differently. Still work in progress, but it works.
Also pass data to prepaint functions in a struct, as there is
already quite a number of them.

It may fail (or "fail") if the window is not mapped or if the geometry
doesn't match, both of which may happen due to the asynchronous
nature of X.
