The Solution:
/**
* An extendable collection of functions for defining symbol paths.
*/
symbols: {
'cross': function (x, y, radius) {
var r = radius,
e = r/4,
a = e / Math.sqrt(2),
b = Math.sqrt( ((r+a)*(r-a)/2) + ((a*a)/4) ) - (a/2);
return [
M, x - a, y,
L, x - a - b, y - b,
x - b, y - a - b,
x , y - a,
x + b, y - a - b,
x + a + b, y - b,
x + a, y,
x + a + b, y + b,
x + b, y + a + b,
x, y + a,
x - b, y + a + b,
x - a - b, y + b,
'Z'
];
},
