The Dasher class takes a series of linear commands (moveTo, lineTo, close and end) and breaks them into smaller segments according to a dash pattern array and a starting dash phase.

Issues: in J2Se, a zero length dash segment as drawn as a very short dash, whereas Pisces does not draw anything. The PostScript semantics are unclear.
