A new object class, Path, allows you to have multiple paths open for definition simultaneously. Formerly, calling the beginPath() method to start a new path would lose the path that was previously open. You can now create multiple Path objects, assign them to variables, and switch from one to another without losing the one you were previously working on. In particular, this simplifies hit-testing by eliminating the need to explicitly rebuild every path that might be hit.
