Description
When having a transformation matrix ( scaling ) for drawing a painter path with a cosmetic pen, curves ( circles, ellipses ... ) are interpolated wrong.
The attached code demonstrates the problem, the attached screenshot shows what's going wrong.
The same issue happens when drawing to an FBO, what indicates a problem of the OpenGL2 paint engine.
