- faces/piechart: Use GraphicalEffects.Glow for rendering outline of compact text
Apparently using style Text.Outline leads to some pretty bad text rendering. So instead use Glow from GraphicalEffects to achieve a similar effect but one that's smoother. Unfortunately this uses deprecated API because MultiEffect turns out to be completely unusable.
