| Utilitiy class for length calculations of paths. |
| <p> |
| PathLength is a utility class for calculating the length |
| of a path, the location of a point at a particular length |
| along the path, and the angle of the tangent to the path |
| at a given length. |
| </p> |
| <p> |
| It uses a FlatteningPathIterator to create a flattened version |
| of the Path. This means the values returned are not always |
| exact (in fact, they rarely are), but in most cases they |
| are reasonably accurate. |
