* \short Effects that can be inserted into a Path.
* An effect is a special object which can perform
* transformations on the specified path. Examples may include simple
* modifiers such as fading or pitch shifting, or more complex mathematical
* transformations.
*
* In order to use an effect, insert it into the path as follows:
* \code
* Path path = Phonon::createPath(...);
* Effect *effect = new Effect(this);
* path.insertEffect(effect);
* \endcode
*
* The effect will immediately begin applying it's transformations on
* the path. To stop it, remove the Effect from the path.
