-- All drawings span 100% of some conceptual 'page width' and divide it up
-- into 256 parts. `drawingw` describes their width in pixels.
drawingw = 400  -- pixels
function pixels(n)  -- parts to pixels
  return n*drawingw/256
end
function coord(n)  -- pixels to parts
  return math.floor(n*256/drawingw)
end
