A path is a line with zero or more curves, finite length, and zero width. A stroked path is a path with a non-zero width. Stroke expansion is going from a path to a stroked path. Turns out that the math is quite complex. I'm in search of a precise and consensus definition of a path with non-zero width... does anyone know where that is in the svg spec?
