    /** intervals: array containing an even number of entries (>=2), with
         the even indices specifying the length of "on" intervals, and the odd
         indices specifying the length of "off" intervals.
        count: number of elements in the intervals array
        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.
