inset(d=1)             - creates a polygon at an offset d inside a 2D shape
outset(d=1)            - creates a polygon at an offset d outside a 2D shape
fillet(r=1)            - adds fillets of radius r to all concave corners of a 2D shape
rounding(r=1)          - adds rounding to all convex corners of a 2D shape
shell(d,center=false)  - makes a shell of width d along the edge of a 2D shape
                       - positive values of d places the shell on the outside
                       - negative values of d places the shell on the inside
                       - center=true and positive d places the shell centered on the edge
