Hello. I am wondering if I have perhaps found a bug in Qt's SVG rendering. The attached SVG was produced by the attached MetaPost code. They are just a few curves with the respective Bezier control handles marked.
For some reason Qt is not displaying the control points which are drawn as big blue circles at the end of the handles. Opening the file in Inkscape, Firefox etc indicates that it is well formed SVG because those apps show the control points correctly. However if I try to display this SVG using QSvgWidget, or using the SVG Viewer example distributed with Qt, the control points are not displayed. Is this a bug and should I report it? Or is there something else afoot? BTW I'm using Qt 4.8.1 on Kubuntu Precise. Thanks. -- Shriramana Sharma

draw q ;
