## button-black-border

Arguments: multi-picture-button

Returns (or sets with setf) the value of the button-black-border property of `multi-picture-button`. This value determines whether a thin black border is drawn around each button of the control.

The black border is independent of the button-3d-border, which is drawn inside the black border if both are specified. The borders are drawn around the padding of each button but not around the spacing between the buttons.

button-black-border is a property of the `multi-picture-button` class.
