• always include the fill, to help renderers that can't cope with CSS styles
• fix rendering of multiline labels: + lineheight is 18px vs 1em to not have the lines drawn together + no longer contain a spurious empty last <tspan>-pair
• reorder output order of elements: first groups, then nodes, then edges
• correct the displacement on edge end/start points for wide/broad/bold edges

• put the link around the node shape, not just the text. Makes it easier to hit the link.
• nodes with shape: point get a link, too (although the area is tiny)

2006-01-01 v0.16 Tels 72 tests

• require Graph::Easy v0.38
• use $self->angle() to get the correct shape rotation

2005-12-10 v0.14 Tels 72 tests

• require Graph::Easy v0.35
• quote "&", "<", ">" and '"' in links and titles (Thanx Mutante!)
• add "xlink:show" and "xlink:target" on links to open them in a new window (but Firefox ignores this anyway, see mozilla bug #315389)

2005-12-04 v0.13 Tels 72 tests

• require Graph::Easy v0.34

• don't generate invalid SVG on labels/node names with "--", "&", "<" or ">"
• limit precision on edge-lines and arrows to 2 digits (instead of 4)
