Fill a contour given by a closed path

val draw_pic : Picture.t -> t

val externalimage : 
  string ->
  [ `None
  | `Width of Num.t
  | `Height of Num.t
  | `Inside of Num.t * Num.t

type vposition = [

val label : ?pos:position -> Picture.t -> Point.t -> t

label ~pos:`West pic p puts picture pic at the left of the point p

val dotlabel : ?pos:position -> Picture.t -> Point.t -> t

Works like label, but puts a dot at point p as well
