QStroker: Fix erroneous SvgMiterJoin behavior for parallel lines
QLineF::intersect() yields an undefined intersectionPoint for parallel
lines. Thus if the distance to 0,0 is shorter than the current miter
limit, we would draw a triangle to 0,0.
Handle this by not drawing the triangle for parallel lines.
This matches the behavior of Qt::MiterJoin.
