    /** 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. This array will be
         copied in Make, and can be disposed of freely after.
        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.
