### Set style textbox

Syntax: set style textbox {opaquetransparent}

                             {{no}border {<bordercolor>}}{linewidth <lw>}
                             {fillcolor <color>}
                             {margins <xmargin>,<ymargin>}

This command controls the appearance of labels with the attribute 'boxed'. Terminal types that do not support boxed text will ignore this style. Note: The current implementation is experimental; details may change. Implementation for some terminals (svg, latex) is incomplete. Most terminals cannot place a box correctly around rotated text.
