142aab2e24 Introduce an EffectsHandler::animationsSupported -> bool
Summary:
A new method to tell the effects system whether the compositor scene
is able to drive animations. E.g. on software emulation (llvmpipe) it's
better to not do any animations at all.

This information can be used by effects to adjust their behavior, e.g.
PresentWindows could skip transitions or effects can use it in their
supported check to completely disable themselves.

As a first step all scripted effects are considered to be unsupported
if animations are not supported. They inherit AnimationEffect and are
all about driving animations.

The information whether animations are supported comes from the Scene.
It's implemented in the following way:
 * XRender: animations are always supported
 * QPainter: animations are never supported
 * OpenGL: animations are supported, except for software emulation

In addition - for easier testing - there is a new env variable
KWIN_EFFECTS_FORCE_ANIMATIONS to overwrite the selection.

77fff7af6a [kwin] Port away from deprected KCoreConfigSkeleton::readConfig
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.

76efe517a7 Turn built-in effects into a library kwin links against
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.

[1] QElapsedTimer around the loading code, start kwin five times, take
average.

b01f5684c5 Remove not needed includes from kwineffect header files
Only include what's actually needed in the headers. This causes of course
some additional needed includes in some implementation files.

6d2dfe06e7 Introduce dedicated OpenGL1 and OpenGL2 compositing types
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.

fe4329a252 Only call active effects in the effect chain
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.

f213b7da70 Drop KWin::TimeLine from kwineffects
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.

e355700e6e EffectsHandler emits windowDeleted signal

into a windowDeleted signal.

0b85768ec5 EffectsHandler emits windowClosed signal
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.

ab6f2ba1fd EffectsHandler emits windowAdded signal
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.

cbe8b6fb93 * replace qhash by qmap and avoid side-effect prone QHash::operator[]
* use TimeLine data memeber instead pointer to prevent leaking
* only setTransformed() if there's really a current animation, not if "a window we know is mapped"
* therefore use a poperty to know whether the effect manages a deleted window
* set the TRANSFORMED flag in prePaintWindow as it should be

5fe0ef985d Add new "sheet" effect based on fade. This effect animates appearing and disappearing of modal dialogs. Inspired by a Compiz Fusion effect (http://smspillaz.wordpress.com/2008/12/23/they-say-when-you-start-something/) and seems to be a Mac OS X animation as well.
