GDToolkit 2.0 - new release

[Maurizio Pizzonia]

We are very happy to announce release 2.0 of GDToolkit, an
object-oriented 
library for handling and drawing graphs. Main improvements to release
1.0 are: 

       Dual-graph generation 
       Planarizer supporting constraints 
       Extension of min-cost flow with lower bounds 
       Batch layout generator (BLAG) 
       Refinement of the end-user graph-editing tool (GRID)
       Constraints management 
              No crosses on the specified edge 
              No bends / any number of bends on the
              specified edge 
              Only right / only left bends along the specified
              edge 
              Specified set of nodes on the same face 
              Specified ordered set of nodes on the same
              face 
       Quasi-upward drawings 
              Slow upward layout generator (minimum number
              of bends over all the planar embeddings) 
              Slow compactor (based on a min-cost-flow
              technique) 
       Orthogonal drawings 
              Slow compactor (based on a min-cost-flow
              technique) 
              Compaction-refinement heuristic 
              Extension of orthogonal algorithms for nodes
              with arbitrary degree
