| * parallelogram shapes. | |
| * Six floating point numbers are provided and the parallelogram | |
| * is defined as the quadrilateral with the following vertices: | |
| * <pre> | |
| * origin: (x, y) | |
| * => (x+dx1, y+dy1) | |
| * => (x+dx1+dx2, y+dy1+dy2) | |

| * => origin | |
| * </pre> | |
| * The four u[xy][12] parameters are the unsorted extreme coordinates | |
| * 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). | |
