[pstricks] \pspolygon and dimen=inner

None of my polygons have crossing lines, so they do enclose 'inner' space.

A very simple example

\pspicture(4,4)
  \pspolygon(1,1)(1,4)(2,3)(3,4)(4,2)
\endpspicture

If it is not possible to use dimen=inner is there some other way of gaining 
the same effect?
