[Qt-interest] Antialiasing via OpenGL v2 engine onto a QGLWidget (or FBO)

[John Clayton]

Hi All - 

I'm using OpenGLV2 engine with QGraphicsVIew - and when I use QPainterPath to draw a rounded rect, the edges on the rounded parts are very jagged.  I'm using setSampleBuffers(true) for the QGLWidget's QGLFormat - and also using both QPainter::AntiAliasing and QPainter::HighQualityAntialiasing - is there something else i should do to make it anti-alias those corners properly?  

Cheers and have a good new year!
