failure in doc of QPainter::setPen(const QColor&)

Doc of QPainter::setPen(const QColor&) says:

"Sets the painter's pen to have style Qt::SolidLine, width 0 and the specified color."

Width 0 is not true any more since by default in Qt 5, pens are not cosmetic any more but have width 1. QPainter::setPen(const QColor&) is using QPen constructor without width parameter, which will result in a pen width of 1.

So doc must be changed: "width 0" -> "width 1".
