For a complete documentation of new functionality refer to:
http://community.kde.org/KWin/Shadow
The current implementation includes a new Shadow class and Toplevel
holds a pointer to an instance of this class. The Shadow class reads
the data from the X11 Property. There is one extended class located
in SceneOpenGL to render the shadow.
Compositor is adjusted to include the shadow region into the painting
passes.
Implementation for XRender still missing and Shadow needs to respond
to size changes of the Toplevel to update cached shadow region and
WindowQuads.
The branch contains the first step in reworking the kwineffects
library. This includes:
* replacing virtuals by signals and slots
* dropping some unused methods
* remove KWin::TimeLine
More to come.

It is not used by any effect, so we save one complete go through
all effects pass on each window damage.
The functionality which could be provided by this hook can also be
implemented using the window damaged signal.
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 should improve v'syncing, maybe v'synced "smoothness"
remaining and exposed issue are "dirty textures" w/o damage events (see the requst description)
can be diminished by increasing MaxFPS above the fastest update (or shadowed below the slowest one)

This provides a significant performance improvement especially for Present Windows.
Whenever a lanczos resampling is done the resulted texture is cached, till the
window is damaged or a texture of different size is required. This means that
for a taskbar thumbnail the resampling only occurs once unless the window is damaged
and for present windows it only occurs when the windows are resized and then only
after the windows have already been moved. Highlighting windows does not cause
a resampling any more.

With Intel drivers currently the self check at KWin startup fails (no idea why) and KWin falls back to XRender. This is probably an explanation for all the complaints about slow kwin in 4.5 and the missing effects. So let's fail and make it possible to restart compositing via systemsettings and alt+shift+f12.
Nevertheless it would be nice to fix the the failing selfcheck...

also detect not-so-bad-but-still-slow paint times over a longer
period of time, i.e. the old check is for systems which are pathetically
slow, this one is for systems that are just slow. Possibly may need
tweaking for cases like high system load, but right now it seems
that e.g. a compilation running cannot trigger this check because
it cannot cause many long repaints in a row.

If three successive ones take more than 1 sec, suspend compositing,

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
