| phase: offset into the intervals array (mod the sum of all of the |
| intervals). |
| |
| For example: if intervals[] = {10, 20}, count = 2, and phase = 25, |
| this will set up a dashed path like so: |
| 5 pixels off |
| 10 pixels on |
| 20 pixels off |
| 10 pixels on |
| 20 pixels off |
| ... |
| A phase of -5, 25, 55, 85, etc. would all result in the same path, |
| because the sum of all the intervals is 30. |
| |
| Note: only affects stroked paths. |
