// take SVG commands and draw this path to HTML5 canvas

// commandList should look like that: [ { marker: "M", values: [ 10, 10 ] }, 
//                                      { marker: "l", values: [ 5, 7 ] },
//                                      { marker: "C", values: [ -5, 7.2, .3, -16, 24, 10 ] },
//                                      . . .
//                                      { marker: "z", values: [ ] } ]
