- bring CSS lexer to the CSS2.1 spec (http://www.w3.org/TR/CSS2/syndata.html)
- CSS override rules are broken. For example, text-offset-y and text-offset
  should override each other, but currently they are mixed upon rendering.
  Does it matter?
- Fixing of label positions should include some margin
- _BRUM_XXX_H -> _LEO_XXX_H

- Interesting tags:
amenity = kindergarten
bridge = yes
historic = archaeological_site
place = islet
railway = crossing
railway = level_crossing
tunnel = culvert
tunnel = yes
