roundedCorners support in drawPolygon

Here is an interesting algorithm for drawing polygons with rounded corners that can be implemented without Bezier curves.

That's interesting. Though I think cubic splines might have more control (without having looked at that article too close). I started writing a Path class with lines and cubic splines implemented for outline drawing so far, but then work started up again and I have pick away at it a bit more slowly now.

Right. At the end of the linked article and in SO answers there is a variant based on Bezier curve too
