    Description

      QPainter::drawPath fails to draw a QPainterPath that contains a tiny ellipse. If the size gets small enough, nothing is drawn. At the "edge of failure" a strange looking figure is drawn (shown in the attached image).

      The attached files contain a small example program that shows the problem.
