2006-07-12	Previously graph layout was done using the Kamada-Kawai layout algorithm	Tim Dwyer	1	-115/+0
	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.

2006-05-23	make loop var unsigned etc, remove compiler warnings	Ralf Stephan	1	-7/+6

2006-05-10	Apparently a problem was reported with one of the test cases.	Tim Dwyer	1	-20/+25
	I can't reproduce the problem, however solve_VPSC code in inkscape was getting quite out of date with that in www.sf.net/projects/adaptagrams. I've updated the code, which may fix the problem, or at least if it's reported again then I'll know it's still an issue. (bzr r803)

	Okay, I'm basically undoing the last commit that SVK screwed up. All this work is not mine, it was done by other people. Sorry to mess things up. (bzr r92)

2006-02-06	Stupid bug in generate-constraints events comparison test fixed	Tim Dwyer	1	-1/+1
	(bzr r84)
2006-01-26	Fixed bug to do with comparison of invalid constraints in pairing heaps.	Tim Dwyer	1	-0/+2
	Also numerical problem with constraint generation fixed. (bzr r30)
