| 10 | * This is mostly like GnomeCanvasBpathDef, but with added functionality: |

| 11 | * - can be constructed from scratch, from existing bpath of from static bpath |
|---|
| 12 | * - Path is always terminated with ART_END |
|---|
| 13 | * - Has closed flag |

| 14 | * - has concat, split and copy methods |
