[pstricks] funny behaviour of pstArcOAB

[Doris Wagner]

thanx, also in my case it works fine now.

the reason why I _didn't_ use \pstGeonode was (apart from the fact  
that \pnode is shorter) that I didn't know that it is possible to  
define something like this:

\pstGeonode([offset=-5]C){H}

I thougt this is only possible with \pnode.

A little suggestion here: in the _NEXT_ pstricks book, there could be  
a chapter that illustrates how to use \pstGeonode in the above way.  
constructing a point on a line perpendicular to another line (through  
a given point) is REALLY euclidean...
