> Currently GeoPainter renders Polygons wrong if they have an outline pen and are filled (think of buildings): A QPolygonF is created from the outer boundary and the inner rings are subtracted. Now QPainter paints the stroke of such Polygons by connecting each point, leading to unwanted connections between the outer boundary and the inner holes. See http://i.imgur.com/25rjs.png (from Ander).
