## Rounded_polygon
Draw a polygon with rounded corners. Each element of the vector is the XY coordinate and a radius. Radius can be negative for a concave corner.
Draw a polygon with rounded corners. Each element of the vector is the XY coordinate and a radius in clockwise order.
Radius can be negative for a concave corner.
Because the tangents need to be calculated to find the length these can be calculated separately and re-used when drawing to save calculating them twice.
