10c07080bb Notify effects when the screen gets locked 
EffectsHandlerImpl starts to monitor DBus for the screen being locked and
provides this information to the Effect system by allowing them to ask
whether the screen is currently locked and by emitting a signal when the
screen gets locked/unlocked.

This information is needed to ensure that no private data is shown on the
screen. The following effects are adjusted:
* taskbar thumbnails
* thumbnail aside
* mouse mark
* screen shot

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.

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.

cbb4248a2a Use a high quality lanczos filter to scale the window thumbnails when 
GLSL shaders are supported.

Currently disabled when the NVIDIA driver is used because of a driver
issue that will need to be worked around.

846496d2c1 Cleaned up the effects/ directory by moving each individual effect into 
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
