| * origin: (x, y) |
| * => (x+dx1, y+dy1) |

| * of the primitive in user space. They may have been generated by a |
| * line or a rectangle so they could have u[xy]2 < u[xy]1 in some cases. |
| * They should be sorted before calculating the bounds of the original |
| * primitive (such as for calculating the user space bounds for the |
| * Paint.createContext() method). |
