shown, but are now always behind the desktop.
Also, it makes the tabbox more consistent.

The closeview is not hidden because that causes
invalid textures (apparently QML related) and
deleting/recreating causes massive I/O overhead
on effect invocation.
As last resort, the window is "hidden" by moving
it out of the root window geometry.

This change allows to include the effect_builtins.cpp into the build of
e.g. a kcm without having to link against all effects.
The use case for this is when one needs to resolve just the name of an
effect without wanting to hard code the name.
This is a kind of workaround for the flicker of fading out windows.
When a window is faded out it is a deleted and can by that be used
as a sufficient solution to work around the problem.

Prior to this commit we didn't know if mipmaps were going to be used
when we created the GL texture, which meant that we couldn't tell the
driver whether to allocate storage for mipmaps or not.
This resulted in one of two things happening depending on the driver;
either it would allocate storage for mipmaps that in most cases would
never be used, or it wouldn't and would later be forced to reallocate
the texture when mipmaps were added.
By adding this parameter we can now explicitly tell the driver how
many mipmap levels will be used.
The parameter is only added to the non-image constructor for now. The
image constructor is changed to only allocate a single level, which
matches how textures created from images are used in kwin. This may
need to be revisited in the future.
This code is broken in a number of different ways; firstly by assuming
that the mipmaps need to be regenerated when the texture filter has
changed. Secondly by preventing mipmaps from being specified by other
means.
This commit removes the code from bind() and adds a generateMipmaps()
method instead.
The cube effect was relying on paintWindow() using the generic shader
without explicitly telling it to do so. This makes the cube effect
work with dynamic shaders.
Instead of getting size from displayWidth() and displayHeight() use
the information we have from Screens. This means there is only one
place to have the information and by that we can ensure that all
components use the same data to rely on. displayWidth/displayHeight
seem to provide the wrong information when unplugging an output
without disabling the output. This results in rendering artefacts.
But KWin::Screens has the correct information available.

Scripts and scripted effects can provide a ui file which gets loaded at
runtime. Obviously such a ui file is not translated. This introduces
quite a hack to load the translated strings.
In the metadata.desktop file the scripted component can provide a key
X-KWin-Config-TranslationDomain. The genericscriptedconfig tries to
locate the metadata.desktop file and reads this entry. If it is present
we extract all string properties of the loaded UI and pass them through
ki18nd.

DesktopGrid uses PresentWindows Effect as a proxy effect. Instead of
hard coding the name of the Effect let's use the name resolving provided
by BuiltInEffects.
xcbutils.h has quite a few inline only implementations such as Xcb::Atom,
the Wrappers, Xcb::Window and the convenient methods. Thus there is
nothing wrong with using it from the built-in Effects.
Xcb::Atom is used in Glide and Logout Effect to get the atom. To keep the
logic of the existing code it got extended by a bool isValid() which
gets the reply and returns true if the atom is set.

This removes all the hacks to add kwin4_effect_ to the name of the Effect

All KCMs and KWin core use the BuiltInEffects namespace to find and
interact with the effects. There is no information left in the desktop
file which are of usage. Thus they can be removed.
The EffectData in BuiltinEffects is extended by all the data needed for
the desktop effects KCM:
* display name
* comment
* category
* video-url
* exclusive group
* internal
This information is taken directly from the desktop files.
The Built-in effects are now also resolved through the BuiltInEffects
namespace and the KServiceTypeTrader query is adjusted to only find the
scripted effects.
Unfortunately this introduces another round of adding "kwin4_effect_" to
load and save the effects correctly. This will be removed once all KCMs
are adjusted to use the new BuiltInEffects.
Instead of having several hashes with data about the built-in effect,
we use a struct EffectData which contains the name, the enabled by
default state and function pointers to create, supported and check
enabled by default. There is one static vector with all the data
specified which is ordered by the BuiltInEffect enum. Thus an enum value
can be used as an index to the data.
In addition it's no longer resolved around QByteArray, but uses QString.
REVIEW: 117354
So far the effects could just use the connection() and rootWindow()
provided by kwinglobals. Thus an internal detail from KWin core is
accessed directly.
To be more consistent with the rest of the API it's wrapped through the
EffectsHandler and with a convenient method in Effect.
The connection() is provided as xcbConnection() to free the very generic
name connection which could create confusion once we provide a wayland
connection to the Effects.
The rootWindow() is provided as x11RootWindow() to indicate that it is
for the X11 world.

If the property changes the animation data is updated. As the last
property change event will definately be delivered before an unmap notify
we can be sure that the animation data is up to data. Reading the
property again does not have any advantages.
By removing it we get rid of at least one roundtrip to the X Server and
it fixes one failed GetProperty error when it tries to read the property
for an already destroyed unmanaged.

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.
For each effect the value from the desktop file is added. This will
allow to query all effects which need to be loaded without looking for
the service files.
The functionality is to check whether the effect should be enabled by
default. It's not about whether the effect is enabled by default. This
is also needed as it's currently still taken from the plugin data.
For each effect there is an enum value. The internal mapping of effect to
create, supported and checkDefault is switched to the enum value, though
the methods for the name based variants are still available.
XRenderUtils are split out of kwineffects and are an own library just
like kwinglutils is an own library.
The library gets always build and is linked in KWin core unconditionally
(as it's used in outline) and conditionally in kwineffects (PaintClipper)
and the built in effects depending on XRender build option.
Affected effects
* Blur and Contrast Shader to get atom name
* Glide effect for the slide atom
* startupfeedback for cursor size - read from config now and cached

Most is just switched to the ::read(). That should be enough for all the
Effects which have a KSharedConfig::Ptr underneath. If not we just need
to find a good place to put the reload.
Instead of using EffectsHandler::sendReloadMessage we generate the dbus
interface in each plugin and call the reconfigure slot directly. That way
it's more type safe and we don't need to link kwineffects from the
configs.
REVIEW: 116875
There are no advantages for the effects KCM to have all the effect
config modules in one plugin.
By having a plugin per effect we can use the KPluginTrader to easily
find the configuration plugin for a given effect and load it.
To make this possible the following changes are done:
* config_builtins.cpp is deleted
* add_subdirectory is used for all effects which have a config module
* toplevel CMakeLists.txt contains the sources again for the effects
which have a config module, but effects which don't have a config
module are still included and thus the macro is still used
* plugin created for the config module, name pattern is:
kwin_effectname_config
* plugin installed to ${PLUGIN_INSTALL_DIR}/kwin/effects/configs
* desktop file adjusted to new plugin name and keyword removed
* desktop file converted to json as meta data and no longer installed
* Uses K_PLUGIN_FACTORY_WITH_JSON
* Macros for config are dropped from kwineffects.h

Implemented in KWin core to forward to new global shortcut system. This
method should be extended/changed once we go to Qt5/KF5 to make the usage
easier (no more KAction).
Each global shortcut in the effects makes use of this new method.
Painting was already disabled in the effect inside ksmserver, thus it
was more or less dead code. Let's remove it completely.
This also allows to remove the "temporary" hack inside KWin's logout
effect.

X-KWin-Internal should be used for effects which are either internal
to KWin and are configured at a different location in KWin. Examples
are:
* CoverSwitch - configured in WindowSwitcher KCM, but not FlipSwitch
as that one has a non WindowSwitcher mode
* window geometry - configured in moving
And it should also be used for helper effects to the overall
kde-workspace module. Examples are:
* Dashboard - required by Plasma
* KScreen - required for KScreen
* Screenshot - required by KSnapshot
Why a new category and not the already existing NoShow property?
The idea is to just filter on the effects in the list. Thus it should
be possible to show them. But NoShow is clearly intended to not be
shown at all.
REVIEW: 116754
Lambda connections are tricky: they do not get automatically
disconnected when the captured [this] gets destroyed, but they get
disconnected when the sender object gets destroyed.
Thus the slide effect was crashing if it got disabled and a window
got deleted, because the connection was still present and tried to
access the destroyed this pointer.
To circumvent we need to pass this as context object.

All effects with
X-KWin-Exclusive-Category=category
are considered as mutual exclusive for specified category. So far this is
just a hint for the GUI representation. Such effects should get a
radio button while effects in the same category without that property
or with it set to false should get a checkbox.
As a first step the desktop change animation effects use this property
and are put into a new category "Virtual Desktop Switching Animation".

KWin already has a de facto OpenGL 2 dependency through QML. Combined
with the fact that the OpenGL 1 backend is basically unmaintained and
also unused, it's better to remove it for the new major release.
This change includes:
* Removal of cmake option KWIN_BUILD_OPENGL_1_COMPOSITING
* Removal of KWIN_HAVE_OPENGL_1 compile option and all code
ifdef'ed with it (partially removal of if-else constructs)
* Removal of CompositingType::OpenGL1Compositing (flags are kept
as a core flag should get introduced)
* Driver recommendation for OpenGL1Compositing changed to XRender
(should be evaluated whether the drivers can provide GL2)
* Removal of configuration option "GLLegacy"
* Removal of fooMatrix function in kwinglutils
* Removal of ARBBlurShader
* Removal of legacy code path in GLVertexBuffer
* Removal of GLShaderManager::disable
* if-blocks with ShaderManager::instance()->isValid() removed

Rational behind this change is that displayWidth and displayHeight are
X specific API calls in kwinglobals. For the future it's easier to only
rely on functionality which goes through the EffectsHandler API which
allows easier adjustments in KWin core.
displayWidth() and displayHeight() are only used to get the size or the
complete rect of all screens. This is also provided by:
effects->virtualScreenGeometry() or
effects->virtualScreenSize()

This seems like a more proper fix for the flickering issue in the
sliding popups effect. The problem is that slidingpopups grabs the
window in windowClosed, the fade effect checks it there, which makes
it racy.
In my tests, I've not seen this problem with the WindowAddedGrab, but
as far as I understand, the problem may well be present there as well.
(And my proposed trick doesn't work.) I've not seen this happening in my
debugging, however. The problem there is also less visible since the
transparency curves go into the same direction, and are more "in line
with each other".
So, fix: Move the setData(WindowClosedGrabRole, ...) call from
windowClosed into windowAdded, which makes sure it's set whenever the
window goes away.

This fixes the sliding popups losing their contrast effect when
animating, less flicker.
In this patch, we temporarily force the contrast effect on, but only if
it hasn't been explicitely disabled. As soon as the animation stops, the
force flag is disabled again. For disappearing windows, we just set the
flag in the same way, but skip over the bookkeeping, since the window is
going to be deleted, anyway.
REVIEW:115902
Without setting the property, Plasma's panel and dialogs lose the
backgroundcontrast effect during slides, which makes them flicker.
As the panel is shown on screen all the time, this is quite a visible
bug. To fix this, when the slide effect is started, we check for window
types and properties of each window, and force the blur flag on if it's
unset.
If the background contrast flag is set to false, we leave the window
alone assuming that there's a reason to force it off. Windows that
are newly added during the slide get the same treatment, so something
popping up while sliding (such as the desktop switch OSD) also gets
the background effect applied.When the effect stops or is interupted, we
unset what we've set, and clean up our internal bookkeeping.
Thanks Martin and Thomas for the thorough review!

As all effects have always been compiled into the same .so file it's
questionable whether resolving the effects through a library is useful
at all. By linking against the built-in effects we gain the following
advantages:
* don't have to load/unload the KLibrary
* don't have to resolve the create, supported and enabled functions
* no version check required
* no dependency resolving (effects don't use it)
* remove the KWIN_EFFECT macros from the effects
All the effects are now registered in an effects_builtins file which
maps the name to a factory method and supported or enabled by default
methods.
During loading the effects we first check whether there is a built-in
effect by the given name and make a shortcut to create it through that.
If that's not possible the normal plugin loading is used.
Completely unscientific testing [1] showed an improvement of almost 10
msec during loading all the effects I use.

We need to use the varying_in/out variables, the code was a little

really generated.
