Main motivation for this rewrite is the fact that the login effect had
been designed under the assumption that there is only one login splash
window. This assumption does no longer hold with the QML based splash,
which creates a window per screen.
By using a JavaScript based effect, the animation effect is implicityly
used which supports animating multiple windows at the same time in a
better and safer way.

This includes:
* getting cursor image through xcb_xfixes
* using xcb_image_get for reading screen content in xrender case
* using xcb_put_image to upload the generated screenshot into shared xpix
Overall this means that QPixmap as an X Pixmap wrapper is no longer used.

The main difference is that the activation of an edge is no longer
broadcasted to all effects and scripts, but instead a passed in slot of
the Effect/Script is invoked.
For this the EffectsHandler API is changed to take the Effect as an
argument to (un)reserveElectricBorder. As callback slot the existing
borderActivated is used.
In addition the ScreenEdge monitors the object for beeing destroyed and
unregisters the the edge automatically. This removes the need from the
Effect to call unregister in the dtor.

First XRender effect which gets ported over. Therefore required bits are
added to CMakeLists.txt.
Port to xcb is luckily rather straight forward. Though the QPixmap usage
needs to be replaced by xcb_pixmap_t together with a XRenderPicture.
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.

Instead of each effect, which needs to announce support, having custom

The methods takes care of creating the atom if it has not already done

effects to announce the same property without getting in conflict with
each other.
As a further convenience the property is automatically removed when the
effect is unloaded, so less things an effect author has to care about.

The ownership for virtual desktops is moved from Workspace into a new
VirtualDesktopManager. The manager is responsible for providing the count
of virtual desktops and keeping track of the currently used virtual
desktop.
All methods related to moving between desktops are also moved from
Workspace to the new manager, though all methods related to Clients on
Virtual Desktops remain in Workspace for the time being. This is to have
the new manager as independent from KWin core as possible.
An rather important change for the handling of virtual desktops is that
the count and the id of a desktop is now an unsinged integer instead of
an integer. The reason for that is that we cannot have a negative count
of desktops as well as it is not possible to be on a desktop with a
negative identifier.
In that regard it is important to remember that a Client can be on a
desktop with a negative identifier. The special value for a Client being
on all desktops is handled by using -1 as a desktop. For the time being
this is not adjusted but instead of comparing the virtual desktop ids one
should prefer to use the convenient methods like isOnDesktop and
isOnAllDesktops. This would allow in future to internally change the
representation for on all desktops.
This method can be used to get the animationTime in case a configuration
class generated through KConfigXT is used. In general the configuration
stores the magic value 0 for a property "duration". This magic value
indicates that a hard-coded default value should be used.
So the common logic to test the stored value for 0 and then either pass
the stored value or the default value to animationTime is encapsulated
in this method in a generic way.
A MyEffect can use it in the following way:
animationTime<MyEffectConfig>(200);

A decoration can provide the AbilityAnnounceAlphaChannel in addition to
AbilityUsesAlphaChannel. If this ability is provided the decoration can
enable/disable the use of the alpha channel through setAlphaEnabled().
The base idea behind this mechanism is to be able to tell the compositor
that currently alpha is not needed. An example is the maximized state in
which the decoration is fully opaque so that there is no need to use the
translucency code path which would render all windows behind the deco.
In addition also the blur effect honors this setting so that behind a
known opaque decoration no blurring is performed.
Oxygen is adjusted to disable translucency in maximized state and Aurorae
is adjusted to allow themes to enable/disable translucency. For Plastik
translucency and with that also blurring is disabled.

The current API call to animate a window does not feel very JavaScripty.

The logic has already ensured that the ARBBlurShader can only be used
when using the OpenGL1 compositor, the OpenGL 2 compositor needs to use
the GLSLBlurShader.
This change moves the complete ARBBlurShader into a KWIN_HAVE_OPENGL_1
ifdef section.
As a side-effect the ::create method can now return a NULL pointer which
makes more sense then returning an ARBBlurShader in case that the
GLSLShader is not supported.
REVIEW: 106738
If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.
This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.
With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.
E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);
while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.
Given that the Catalyst driver is now supporting direct rendering and by
that can use the OpenGL 2 code path we do no longer need to force
disable the Blur effect and Lanczos filters which used to crash in the
ARB shader path.
The ARB shader path - which can only be used in OpenGL 1 - is kept
disabled for Catalyst.

The ShaderBinder class can be used for the case that a block of code
should be executed with a given Shader being bound. This is useful for
all the cases where there is a if-block for OpenGL2 execution with a
Shader being pushed in the first line to the ShaderManager and popped in
the last line of the block. With the helper this can be simplified to:
ShaderBinder binder(myCustomShader);
or
ShaderBinder binder(ShaderManager::GenericShader);
The ctor of ShaderBinder pushes the given Shader to the stack and once
the helper goes out of scope it will be popped again from the stack.
In addition the helper can take care of OpenGL 1 compositing, that is it
just does nothing. So it can also be used where there is a shared OpenGL1
and OpenGL2 code path where the Shader should only be pushed in OpenGL2.
This basically removes all the checks for the compositing type before
pushing/popping a Shader to the stack.
REVIEW: 106521
The main usage of ShaderManager::isValid was to have OpenGL2 specific
code pathes. Now we have an actual OpenGL2Compositing type and we know
that the ShaderManager is valid if we have this compositing type and we
know that it is not valid on OpenGL1Compositing. This gives us a much
better check and allows us to use the isValid method just for where we
want to check whether the shaders compiled successfully.
In addition some effects require OpenGL2, so we do not need to check
again that the ShaderManager is valid. Such usages are removed.
The CompositingType enum turns into flags and two new values are
introduced: OpenGL1Compositing and OpenGL2Compositing.
Those new values are or-ed to OpenGLCompositing so that a simple check
for the flag OpenGLCompositing works in case of one of those two new
values. To make the generic check for OpenGL compositing easier a method
in EffectsHandler is introduced to just check for this.
The scenes now return either OpenGL1Compositing or OpenGL2Compositing
depending on which Scene implementation. None returns OpenGLCompositing.
Left over from the cleanup which basically resulted in the active window
being put to the inactive's window opacity.

FIXED-IN: 4.9.2
The effect should have had two animations:
* on move resize
* on active/inactive change
But the timeline was adjusted in the prePaintWindow call and the timeline
is effect global and not per window. Which means that for each window the
same time is added. So instead of adding time t each frame t*n with n
being the number of windows got added. So in most cases the animation
ended in the first or second frame which means its not visible.
Through git blame I was able to track down that this incorrect behavior
was introduced in 2008. An animation broken for more than four years
without anybody noticing is probably not required. Because of that it's
dropped from the effect. As this includes quite some code and performance
improvements it goes into the release branch.
A better solution could be implemented, but that should be for 4.10.

There were quite some useless checks like e.g. first checking whether
a window is the desktop and taking a different code path for that case
and in the other code path checking again.
Also using the new introduced boolean values for the checks instead of
comparing floating point numbers all the time.
The effect gets a set of boolean values to check whether it is active for
one of the categories (e.g. move resize, decorations).
This allows to easily check whether the effect is active at all, that is
if all values are at 1.0 the effect will never affect a window.
In all other cases it can be combined with looking at the available
windows to e.g. enable the effect for move resize only when there is a
window which is either moved or resized. This check is performed whenever
an action happens which could cause a window to become inactive.

Our first effect written in JavaScript to replace an existing C++
effect. Fade effect has been chosen as it has shown to be problematic
in the past and would have needed a migration to AnimationEffect anyway.
This reduces the repaints in cases where several blur regions are
stacked on top of each other (e.g. oxygen-transparent) and the topmost
layer needs to be updated (e.g. a blurry window is moved).
The old blur version wrongly marked a cache region as valid with the
reason that this region would never become visible. It didnt matter
because the only case that this region could become visible was a
movement of the window on top, which back then would have forced a
workspace repaint of that region and as such would have invalidated
the cache anyway. With the introduction of addLayerRepaint the
last point is no longer true and we have to track the valid cache
regions more carefully.
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.

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.
REVIEW: 102665
This caused situations in which the shader was pushed but never
popped from the stack as for the latter case there was a check
whether the effect is active.
BUG: 280455
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.
REVIEW: 101977
This is actually a bloody hack by forcing the screen to be
repainted in each frame. This needs to be fixed in a different
way or we at least have to turn blur off by default for GLES in
the next release.
Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

Effect uses framebuffer blit to copy the zoomed are in a scaled
way into an offscreen texture and render the texture after the
rendering. This means instead of two rendering passes we now need
only one pass, but require the blit extension.
Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.

REVIEW: 101318
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.

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.

For what reason ever motion manager thinks that windows are not

So we also have to look on the timeline to decide whether we should

Now wonder the animation was stuttering.
BUG: 274292
FIXED-IN: 4.7.0
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.

useable for Plasma Active:
* blur
* dialogparent
* fade
* login
* outline
* presentwindows

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.

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

repainted causing the garbage.

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.

The effect has been known to cause some problems for quite some time

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
