1752302203 [effects] Use passed through matrix in Blur Effect
The blur effect so far calculated a custom model view projection matrix.
This is not needed as we have the current projection matrix available in
WindowPaintData and EffectFrame.

044e2a05b2 [effects] Properly announce/remove support in blur/contrast if shader fails
Following the approach how it's done for X11: only create the interface
if the shader succeeded to compile and remove support again if it failed
to compile after a reconfigure.

3bbc9436db [kwin] Add a virtual Effect::requestedEffectChainPosition
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.

0c92e1f30c Use translucent/dialogs/background elements where possible
In effects it's obvious that compositing is enabled, so specifying the
translucent element is no problem.

In tabbox a context property "compositing" is injected which decides
whether "translucent" or "opaque" elements should be used. Here the
translucent elements are only used if the Blur effect is available - for
this a new Effect::Feature Blur is introduced and in addition it is
tested whether the theme provides the translucent element.

Also the masking is adjusted to ensure that only the shadow is not
blurred.

Reason for this change is that Plasma theme seems not always to pick up
whether compositing is used when used from inside KWin. It does not cover
the Desktop Change OSD which uses PlasmaCore.Dialog and there we cannot
(yet) inject that we use compositing.

Overall I'm quite unhappy with this patch and I do hope we can fix it in
the proper place in the lifetime of 4.10 and revert this patch.

23f2de009b Effects can provide support information through properties
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.

239d5757f2 kwin: move/resize events shall not force a repaint of all layers
This patch adds a new function Toplevel::addLayerRepaint, that in contrast
to addWorkspaceRepaint does not invalidate every blur texture cache that
overlaps with that region. As the name suggests it rather invalidates the
to the window associated layer at that position. This is especially useful
in the case of move/resize events in combination with oxygen-transparent,
where the altered window is almost always the topmost window and the blur
texture cache of the windows underneath are unchanged.

For the case of fully opaque windows the behaviour of addLayerRepaint
and addWorkspaceRepaint should be same.

3065e6afce kwin/blur: add a proper initialization of the texture cache
This fixes graphical glitches that appear next to the borders of plasma
tooltips. Additionally I added a variable that forces the effect to
drop the cache, which might be useful in the future to fix bugs.

b6478e1b12 kwin: Optimizing Blur Part III
This patch introduces some kind of damage propagation. In the old version of the blur effect
we had to repaint the whole window if sth behind the blurred area was damaged. The new texture
cache, which was introduced by the last patch, gives us the opportunity to only update parts of
blurred background texture. This means that the damaged area can only propagate with the speed
of the blurring radius per window layer.

ef9aeafe0d kwin: Optimizing Blur Part II
This patch adds an optional texture cache to the blur effect such that damaged windows in
front of the blurred region dont trigger a repaint of the whole blurred region which pretty
often results in a avalanche repaint of nearly the whole screen.

ab6f2ba1fd EffectsHandler emits windowAdded signal
All previously existing windowAdded methods are renamed to slotWindowAdded.
EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is
emitted a little bit earlier than the previous direct method call. This might
change behavior.
Another signal is added to Workspace to signal that an unmanaged is added.
