I need to be able to draw a polygon with rounded corners. That is given
(say) an array of points that form the polygon, I'd like to draw it such
that the corners are rounded (the radius needs to be configurable).

How would I go about doing this?

Loop through each point in a set of straight lines
For each each point, then work out the radius distance from the point to the
previuus point and next point, using a bit of trig (look into Math.Atan)

Draw
1. A line from the previous arc (or start point) to the radius - point.
2. An arc from the radius - to the radius + point

The graphicspath class would work best here
