Supported Features:
* move/resize
* active/inactive
* special window type
* window decoration as missing in AnimationEffect
The animations are cancelled when they go into an invisible state (e.g.
desktop changed, minimized) and are set again when the window becomes
visible.
Where a transition is useful, the window gets animated, e.g. start/finish
of move resize.

This effect is controlled by KScreen. It fades out all windows when
KScreen requests this and gives feedback to KScreen once all windows are
faded out. This allows KScreen to adjust the screens in a flicker free
way.

The non-composited part handles the showWithX case with the four small
windows. The composited part shows a translucent QWidget with the
FrameSvg as done by the selection effect frame.
Outline connects to the Compositor toggled signal to switch the mode if
compositing gets suspended/resumed. This works fine also in the case that
the switch happens while the outline is shown. To support this Outline
is now a QObject and created with Workspace as a parent.
Given that the Outline handles both cases by itself, the outline effect
is no longer needed and is dropped together with all the hooks into the
effect system.
Tried to build KWin with enable final: it doesn't work. So if nobody uses
it, we don't need it in the CMakeLists to make it work.
Also it's removed in KF5 which means that removing it right now removes
differences in the build system.

Using a lib variable for:
* own libs
* qt libs
* kde libs
* xlib libs
* xcb libs
and link those groups together in target_link_libraries. This should
make the code easier to read and easier to support in future for some
time both Qt4 and Qt5.
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 conversion from xcb_image_t to QImage still needs some code for not
matching byte order. I'm a little bit unsure about adding the code as I
would not be able to test it.

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.
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.
The logout effect was rather broken. First of all it was
excluded from build if OpenGL ES is present at build time. The
reason for this is that the effect did not work with GLES.
In order to fix that the vignetting is ported over to OpenGL 2
by using a dedicated shader. As well the lod based blur is
added through a dedicated shader and uses framebuffer blit to
get the current rendered buffer before rendering the logout
window into a texture.
Last but not least the isActive method was broken and is fixed
by checking whether the logout window is around.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Some old restructuring caused -DKWIN_HAVE_OPENGLES to no longer be
passed to the compiler, causing OpenGL-specific code to be built
while the libraries to link it were not available.

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.
Most effects would not compile anymopre as they are not adjusted
to changes in the effect system (e.g. change to slots).
Also we have enough proper effects to no longer need some demo or
howto effects.
REVIEW: 103744
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.
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.
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.

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

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.
