Can generate the tool path of pretty much any shape without radial overhangs (I made that term up). Can make errors because of the scratch colour collision detection. Set the shape and the tool radius and then click 'Generate toolpath'.
My method for testing for radial overhangs: Draw imaginary lines coming from the centre of the target sprite, spaced one degree apart. If multiple edges of the sprite cross any one of those lines, then I would call that a radial overhang
