Emboldening is akin to rolling a ball around the perimeter. A ball
sometimes cannot get into features smaller than its size - those
features are indeed removed. This is unavoidable. A huge ball rolling
around any glyph would produce shapeless blob. The larger the strength
of emboldening, the more features are removed.
