This will retrieve the border array. If none is available then it will return the default,
which is [0 0 1]. The array consists of at least three numbers defining the horizontal corner
radius, vertical corner radius, and border width. The array may have a fourth element, an
optional dash array defining a pattern of dashes and gaps that shall be used in drawing the
border. If the array has less than three elements, it will be filled with 0.
