Lyric hyphens have several user-modifiable properties such as length and thickness; this doesn’t allow, however, for further tweaking, for example, rendering hyphens as rounded boxes to better match the font possibly used for LyricText, or even printing hyphens as actual glyphs rather than drawing basic boxes.
This snippet rewrites the LyricHyphen stencil procedure to use a proper glyph – or indeed any arbitrary markup.
