When drawing lines with same begin and end point with width 0 or 1 when using either flatcap or roundcap style, the point is not drawn in either qt4.8.0 or 4.8.1, while it is drawn in qt 4.5 up to 4.7.

Since the points in my application are dynamic and sometimes have different y values, in other situations the points can be equal and I still need a visible single dot/pixel as I rely on the behaviour from previous versions.
