Improvements to graphics effects API after review round.
* Get rid of QGraphicsEffectSource from the public API, instead add
convenience functions in QGraphicsEffect. This way we commit to less
API, and are free to introduce a customizable QGraphicsEffectSource
in a future release.
* Move PixmapPadMode into QGraphicsEffect and tweak the names of the
enum values.
* Make QGraphicsBlurEffect::BlurHint into a bit flag, for extensibility.
