projectile dropped. This only works with a black background.
With an ImageMagick-based implementation, there are no such

code from the Gosu demo that makes it look like craters with
charred rims are left in the earth or the star. In the top code
block, circle and fill create a black circle, and shadow creates
a blurred version of the circle. The second code block
