* Added options for no animation in expo and scale plugins. They skip
  the intermediate fading steps that force several redraws.

  animation: useful when performance is more important than eyecandy.

* Composite: use C++ goodness for managing damaging rectangles
* ccsGSettingsBackend: don't try to update setting if wrapper is not

  profiles
