Initial movement about raphael-sketchpad

Hi Mike-

I updated the code to Version 0.5. It shouldn't have the initial point problem. To see a demo with v0.5, check out http://ianli.com/sketchpad/

find
if (tokens.length > 0) {
var token = tokens[0].replace("M", "");
var points = token.split(",");
path.push(["M", parseInt(points[0]), parseInt(points[1])]);

            for (var i = 1, n = tokens.length; i < n; i++) { //san
                token = tokens[i];
                points = token.split(",");
                path.push(["L", parseInt(points[0]), parseInt(points[1])]);
            }
        }

replace

        if (tokens.length > 0) {
            var token = tokens[0].replace("M", "");
            var points = token.split(",");
            path.push(["M", parseInt(points[0]), parseInt(points[1])]);

            for (var i = 3, n = tokens.length; i < n; i++) { //san
                token = tokens[i];
                points = token.split(",");
                path.push(["L", parseInt(points[0]), parseInt(points[1])]);
            }
        }

draw error in
self.move = function(e, sketchpad) {
if (_drawing == true) {
var offset = $(sketchpad.canvas()).offset();
_points.push([e.pageX - offset.left, e.pageY - offset.top]);

            _c.attr({ path: points_to_svg() });
        }
    };

smal size in
e.pageX - offset.left

Has this issue been resolved? Or is there a known fix? I also have this initial point problem, only occurs in firefox but in both mac and windows, as though it plots one point, plots another at 0,0 and then returns, occurs each time the paper is cleared. Also Ians example of 0.5 doesn't appear to work, have tried crysans suggestions but with no luck. I'm pretty sure its related to self.move and the offset but couldn't say exactly whats the cause. Any ideas anyone?

Think I have managed to fix this issue. Check out the fork I have created.

Also I was having another issue when adding a stroke causing an exception to be thrown from the raphael.js file. Solving this was a simple case of upgrading raphael.js from version 1.4 to 2.1.

i also have sketchpad code up at https://github.com/miketahani/tendermaps-redux, in case anyone needs it. field tested.

Thanks @peterkeating for the fix!

I've updated the code to fix the problem. I only needed to make changes to the Pen object.
