color is always rgba(0,0,0,0) if not given

[dodo]

this problem should be covered by raphael.

for instance http://g.raphaeljs.com/piechart.html has colors but

var raphael_example_pie = function (r) {
    r.g.txtattr.font = "12px 'Fontin Sans', Fontin-Sans, sans-serif";
    r.g.text(320, 70, "Static Pie Chart").attr({"font-size": 20});
    r.g.piechart(320, 240, 150, [55, 20, 13, 32, 5, 1, 2, 10]);
};

doesn't.

its the same piece of code.
