The below change is a recommended error checking / recovery for idiots (like moi) that might call the function with a non-existent string.
Not sure what the philosophy is on mucking the code up with throws and error checks.

widthForString: function( s ) {
if (typeof(s) == 'undefined' || s == null) {
return 0;
}
var width = 0;
for( var i = 0; i < s.length; i++ ) {
width += this.widthMap[s.charCodeAt(i) - this.firstChar] + 1;
}
return width;
},
