`map`	An object of type 'map'.
`points`	A data frame of points to be mapped.

A data frame with (x,y)-positions. The data frame has two columns:

x-dim: The x-position of the corresponding point int the 'points' data frame.
y-dim: The y-position of the corresponding point int the 'points' data frame.
