 <DD>  If true and the node has a pos attribute on input, neato prevents the
   node from moving from the input position. This property can also be specified
   in the pos attribute itself (cf. the <A HREF=#d:point>point</A> type).

+  <B>Note:</B> Due to an artifact of the implementation, final coordinates
+  are translated to the origin. Thus, if you look at the output coordinates 
+  given in the (x)dot or plain format, pinned nodes will not have the same  
+  output coordinates as were given on input. If this is important, a 
+  simple workaround is to maintain the coordinates of a pinned node. The vector
+  difference between the old and new coordinates will give the translation, 
+  which can then be subtracted from all of the appropriate coordinates.
