 ## TODO and ideas
-- Bold
 - Underline overlaps a bit, sometimes causing weird blending
-- Somehow use `<tspan>`/`textLength` to produce smaller output. Maybe `em/ch` CSS units for background rects,
-but seems inkscape do not like `ch`. Would also make it nicer to copy text from SVG.
 - Handle vertical tab and form feed (normalize into spaces?)
 - Handle overdrawing
 - More CSI, keep track of cursor?
