Hmmz.. this works, but afaics it basicly creates a very exact constraint
and doesn't round to a cyclinder boundary. I've solved it in my own
hackisch way like this:

---------------------------------------------------------
constraint = ped_constraint_any( device );
                                                                        
ped_disk_set_partition_geom ( disk, c_partition, constraint,
new_start, new_end ) ;

ped_constraint_destroy ( constraint );
                                
ped_geometry_set_start ( & c_partition ->geom, new_start ) ;
constraint = ped_constraint_exact ( & c_partition ->geom ) ;
---------------------------------------------------------------

The resulting constraint quarantees a fixed start and an endpoint thats
rounded on a cylinderboundary. Although functional, i cannot escape the
feeling this can be done in a more efficient way..

Looking forward to the mass of replies :P
