2 Arrow Toggle Snip
|(require mrlib/arrow-toggle-snip)||package: gui-lib|
Represents a toggle control, displayed as a right-facing arrow (off or “closed”) or a downward-facing arrow (on or “open”).
The size of the arrow is determined by the style (and font) applied to the snip. The arrow is drawn inscribed in a square resting on the baseline, but the snip reports its size (usually) as the same as a capital X; this means that the snip should look good next to text (in the same style) no matter whether base-aligned or top-aligned.
