QPainter::RenderHints are hardcoded in QSVGRenderer

QSVGRenderer is always using Antialiasing but this should be developer's decision.

void QSvgTinyDocument::draw(QPainter *p, const QRectF &bounds)
{
// below lines should be removed
p->setRenderHint(QPainter::Antialiasing);
p->setRenderHint(QPainter::SmoothPixmapTransform);
}
