Fix performance regression in HTML5 canvas stroke()
To solve corner case of stroking intersecting path with a transparent
color we switched the strokePath implementation to using QPainterPathStroker
in Qt 5. Unfortunately this appears to be 100-1000x slower than using
QPainter::strokePath.
This patch partially reverts the change and now only use QPainterPathStroker
when stroking a transparent outline.
