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.

BUG: 303314
FIXED-IN: 4.10
This patch reduces the number of QRegion and WindowQuadList operations
by drawing the opaque and translucent parts of the window within the
same bottom to top pass.

did not publish function & enum in the baseclass, but inlined the accessor
REVIEW: 103232
(cherry picked from commit ecfa39ac3ca1c9823a6b320ff0f7a60ab32f0418)
Instead of calculating the elapsed time from epoch clock, using
a QElapsedTimer as well as reusing the timer object instead of
creating a new one in the scene each frame.

All the functionality of Overlay Window is moved to its own class
OverlayWindow. It is created and owned by class Scene, since almost
all function calls are called from this class.
REVIEW: 101866
This commit merges the two signals clientClosed() and unmanagedClosed() to windowClosed() which
is now provided by Toplevel.
The approriate slots in effects.h and effects.cpp were merges as well, since they did the
same.
The direct method calls of the method windowClosed() in SceneOpenGL and SceneXRender were
removed and are now connected to the appropriate signal in windowAdded().
This commit just makes the declaration of windowClosed() in Class Scene be a Q_SLOT.
The inheriting classes SceneOpenGL and SceneXRender are updated as well.
The method windowGeometryShapeChanged() from the class Scene is now a slot. It is now connected to the signal geometryShapeChanged() which is sent from Toplevel instances Client and Unmanaged.
All direct method calls were deleted.
The method windowOpacityChanged is now a protected slot in class Scene. The implementations in the subclasses SceneOpenGL and SceneXRender are the same. The slots are connected to the singal opacityChanged() from Toplevel. The connection is done in the method windowAdded() in both SceneOpenGL and SceneXRender.
Removes the last bits of the self-check at compositing startup.
It seems like they were only added to XRender because they were
in OpenGL and there they are not available for quite some time.
Also removes the now obsolete disable functionality checks from UI.

by checking the graphicssystem at startup
also avoid pixmap and memory leaking on the xrender backend, validate some pointers
on deletion in SceneOpnGL and avoid attempts to render ::isNull pixmaps
With raster a QPixmap is no longer a XPixmap which fails all code
which assumes that an QPixmap is an XPixmap. Depending on were in
the codebase we either convert such pixmaps to images (OpenGL) or
create a XPixmap and use QPixmap::fromX11Pixmap to get a "real"
pixmap.
It is possible that there are more code pathes were we would need
a XPixmap. Currently tested is basic functionality of no-compositing,
XRender compositing, OpenGl/GLX and OpenGL ES/EGL compositing.
For OpenGL compositing raster might result in performance improvements,
for XRender it is possible that there are regressions when using raster.
By default KWin uses whatever is the default of the system, so we just
no longer enforce native.
Of course it is a bad idea to use graphicssystem OpenGL. As that
is broken anyways in Qt, we do not check for it.
Many thanks to Philipp Knechtges for bringing up the issue, convincing
me that we need it and providing most of the patch.

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
revert vsync strategy, fix timeouts
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.
