If we have OpenGL ES but not OpenGL the KWIN_HAVE_OPENGL is set
causing the first compile pass to fail as it tries to build
against OpenGL. As a solution the first pass links against
OpenGL ES if OpenGL is not found.
This means both kwin and kwin_gles are built against GLES.
Nuno has to decide whether the new option will become default or not, for now it is disabled by default.
You can enable it in effects kcm, now Login effect has a configuration dialog.
It does not (yet) however check for non-fullscreen effects, so they might look weird when this is enabled.

Reflection in a vertical multiscreen setup are kind of broken without
PaintClipper. But we have to ask ourselfe whether CoverSwitch in a
vertical multi screen setup makes sense and whether it's useful to
have reflections in such a setup.
Horizontal multiscreen setup works fine (also with reflections).
We have to set the bit depth of the XPixmap to 32 in order to get
an alpha channel and we have to render the grabbed image using
composition mode Source in order to just copy all pixels to the
destination pixmap.

Since the funtionality of TopMenu did no longer work in KDE4 this feature was

The uniforms textureWidth and textureHeight were only needed for
normal windows. For everything else it was just 1.0/1.0, that is
normalized.
The makeArrays method is changed to produce normalized texcoords
obsoleting the need for these uniforms. So two uniforms less, one
calculation in vertex shaders less and many many lines of code
removed.
At the same time makeArrays is also adjusted to take care of
yInverted of the texture, which is needed as we no longer can use
the enableUnnormalizedTexCoords which did the yInverted transformation.

Actually it's more a hack and should be addressed in the next
release cycle by allowing effects to modify the scene's blend
equation.

For what reason ever motion manager thinks that windows are not
moving during the start animation (but are during the stop animation).
So we also have to look on the timeline to decide whether we should
disable lanczos filter on the windows.
Now wonder the animation was stuttering.

Due to changes in the blur effect, the EffectFrame was flickering
with GLES. This can be worked around by doing full repaints whenever
a window is damagded while boxswitch is active with GLES. The problem
only occurs with the GLES backend due to the way how the buffers are
swapped.
BUG: 272688
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.

The new build option restricts the building of effects to those
useable for Plasma Active:
* blur
* dialogparent
* fade
* login
* outline
* presentwindows
* slidingpopups
* taskbarthumbnails
* screenshot
Additionally all effect KCMs are excluded from building in the
assumption that when building with this option, KWIN_BUILD_KCMS
is turned off.

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[])

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.

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.

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.

The shadow effect is known to be broken since at least 4.5.
It is unfortunately in a state which makes it difficult to maintain
and the architecture has some serious drawbacks. Therefore it is the
best solution to replace the effect with a new and better
implementation. For more information about the new implementation
please see the discussion on KWin mailinglist:
http://lists.kde.org/?l=kwin&m=129607406517609&w=2
This also "fixes" all existing bug reports about the shadow effect.
Most of the bugs will really be fixed when the new shadow system is
implemented, if not it is a new bug and a new report should be created
for it.
Please excuse that we go this unnormal approach to mark bugs as
fixed with code removal.

The usefulness of the snow effect is doubtable and it is rather
difficult to port the effect to the new rendering architecture
introduced with GLES. It is probably easier to rewrite the complete
effect from scratch, therefore it is removed for now.
I might consider readding it for 4.7.
This kind of "fixes" snow related bug reports.

It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.
It uses a generic vertex shader and because of that it needs to
mark all windows which are inverted as transformed.
There is currently a conflict with Lanczos (or thumbnails) and with
the desktop in cube effect.
Rotation is now only handled by the QMatrix4x4 m_rotationMatrix,
so no more need for display lists. Resulting in a cleaner code without
differences between OpenGL 1.x and 2.x/GLES.
The vertex buffer implementation uses the shader manager to decide
whether core painting should be used or not. Shader manager is only
used by shaders using vertex attributes instead of gl_Vertex etc.
This includes quite some refactoring. For the cube cap a VBO is used
instead of glLists and all the required transformations are moved into
paintCap() which makes paintScreen more clean.
Currently the mirroring of bottom texture is still missing and cylinder
and sphere caps are not yet ported to using VBO.
I wouldn't be surprised if it is broken for legacy GL atm.
CoverSwitch uses new concept of combining a custom fragment shader with the
built-in generic vertex shader. This shader is used to render the reflection
plane on top of the reflected windows.
The fragment shader uses two uniform colors for front and back and interpolates
between them based on the texcoords (which are not used for texture lookup).
The reflection plane vertices could be buffered.
Currently working:
* cube slide
* basic cube
* rotations
* reflections
Not working:
* Cube Inside effects
* Reflection plane (needs to be done in a shader)
* cube caps
* sphere/cylinder
* filled in areas in multi desktop
