- * PPath is a wrapper around a java.awt.geom.GeneralPath. The setBounds
- * method works by scaling the path to fit into the specified bounds. This
- * normally works well, but if the specified base bounds get too small then it
- * is impossible to expand the path shape again since all its numbers have
- * tended to zero, so application code may need to take this into consideration.
- *
- * One option that applications have is to call startResizeBounds
- * before starting an interaction that may make the bounds very small, and
- * calling endResizeBounds when this interaction is finished. When
- * this is done PPath will use a copy of the original path to do the resizing so
- * the numbers in the path wont loose resolution.
- *
- * This class also provides methods for constructing common shapes using a - * general path. - *
