    Properly fix the conflicting isnan.h problem:
      1) Update src/2geom/isnan.h to match newest Inkscape src/isnana.h
         (Also commited this change to lib2geom project repository)
      2) Remove Inkscape's src/isnan.h
      3) Update all files to include src/2geom/isnan.h instead of src/isnan.h

- Connectors with end-markers now constrained to point downwards in graph layout

2006-07-14T04:09:40+00:00

 - vpsc namespace added to libvpsc

Previously graph layout was done using the Kamada-Kawai layout algorithm

2006-07-12T00:55:58+00:00

implemented in Boost.  I am replacing this with a custom implementation of
a constrained stress-majorization algorithm.

The stress-majorization algorithm is more robust and has better convergence
characteristics than Kamada-Kawai, and also simple constraints can be placed
on node position (for example, to enforce downward-pointing edges, non-overlap constraints, or cluster constraints).

Another big advantage is that we no longer need Boost.

I've tested the basic functionality, but I have yet to properly handle
disconnected graphs or to properly scale the resulting layout.

This commit also includes significant refactoring... the quadratic program solver - libvpsc (Variable Placement with Separation Constraints) has been moved to src/libvpsc and the actual graph layout algorithm is in libcola.
