def font_spacing
  # Monospace fonts will (read: should) have the same width
  # for every glyph, so we can tell a monospace font by
  # checking if a deduplicated widths table has size == 1:
  # irb(main)> font.horizontal_metrics.widths.count
  # => 256
  # irb(main)> font.horizontal_metrics.widths.uniq.compact.length
  # => 1
  to_ttfunk.horizontal_metrics.widths.uniq.compact.length == 1 ? :monospace : :proportional
