Optimize the region of the screen that's painted in each frame,
and paint the windows top-to-bottom when the damaged region doesn't
intersect any blurred areas.
This fixes most of the rendering issues with cube in multi
screen setups and GLSL backend. For cylinder and sphere the
rendering of areas between screen is currently disabled if
using the GLSL backend. It needs adjustments to use another
vertex shader. Not sure if it is worth the effort.
also rewrite of the regular grid assignment - was
a) a suboptimal implementation
b) required because otherwise broken in desktopgrid proxy mode (which btw. polluted the effect through QHash::operator[])

Warnings were:

By making Dashboard Effect a fullscreen effect the blurring got
accidentially broken (blur ignores fullscreen effects). Reenabling
by setting the force blur role on the dashboard window(s).
Reapplied commit 629e17d18526ccfae3d3579066e8be927a92437d from KDE/4.6.
CCBUG: 259797
As this area was not repainted it caused visual garbage during
animationgs. Most visible with yakuake and a panel at the top.
Offset in that case is the upper screenedge while yakuake is
positioned below the panel. The area of the panel did not get
repainted causing the garbage.
CCBUG: 264765
The not initialized boolean value seemed to have evaluated to true
and causing the animation to stop and therefore the darkening not
to apply.
Giving a default value to the EffectWindow pointer doesn't hurt either.
Patch does not apply to 4.6 branch, because of that only in master.
BUG: 264552
FIXED-IN: 4.7.0
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.
Conflicts:
kwin/workspace.cpp
The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
First a signal is emitted when the user starts a move/resize operation.
During the move/resize operation each geometry change emits an update signal.
Last but not least a finish signal is emitted.
This eliminates the specific method for geometry updates in drawbound resize
mode.
The signal includes the state for horizontal and vertical maximize state.
It would be better to use the enum fro, KDecorationDefines but we don't want
to depend on decorations library.
Wobbly windows is adjusted to use this new signal - it is the only effect
interested in maximize state change.
This needs to be improved in core. Currently ClientGroup does not yet
emit signals, as it would be difficult to connect them. Nevertheless
the effects dependency should be removed.
EffectsHandlerImpl just forwards the signals from TabBox. In order
to have a valid pointer to the TabBox, the TabBox is now initialized
before compositing in Workspace.
QMatrix4x4 accepts data in row-major order, but returns them in
column-major order, which is not documented and because of that
I expected them to be in row-major order.
This commit fixes it and rewrites the shaders to apply the matrix
multiplications in the right order.

1. The I18N_ARGUMENT_MISSING that appears when moving or resizing one
window. The problem happens because when declaring the variables
myResizeString, myCoordString[0] and myCoordString_[1] i18nc tries to
replace %1, %2, %3, and %4, but those arguments are not passed here.
Using #define we avoid the argument passsage.
2. Replace QString::arg() with direct formating, which is better for
performance.
I know we should avoid #define but in this case I think it is the best
option. If anyone has a better alternative feel free to change this
commit.
EffectsHandlerImpl connects to the Workspace signal clientActivated.
The emitting of the signal is slightly moved from before the activation logic
to after the activation logic. This might change behavior in the scripting
component, but the previous code looked wrong.
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.
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.
The first signal used between EffectsHandler and Effects.
The signal is actually emitted by the EffectsHandlerImpl and only
the interested effects connect to this signal.
EffectsHandlerImpl itself is also notified by a signal from Workspace,
allowing to remove one of the many if (effects) checks.
Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
possibly prevents leaking ItemInfos
secure some accesses (selected_window), not sure whether this caused the unreproducable crash when used as proxy in coverswitch

CCBUG: 253079
invert.cpp refers to the apparently removed kwinshadereffect.h,
so it's probably missing out on some sort of porting activity.
