2008-05-22 v0.23 Tels 137 tests - Fix, fix, fix, fix the bugs...
* require Graph::Easy v0.63 (for correct graph attribute output)
* suppress attributes without "-" (like "labelpos" vs. "label-pos")
* output the "font-family" style to support the "font" attribute
* center graph when the graph label is wider than the graph itself
* shift graph by half the border with down and right to prevent the border
from getting cut off
* don't draw end arrows on undirected edges (with more than one cell)
* "rounded" nodes have their corners correctly filled with the background
color (f.i. when inside a group) (Thanx Dieter Wunderer!)
* quote "&" in links (Thanx Emmanuel Quevillon!)
* links on edge labels were missing (Thanx Emmanuel Quevillon!)
* tweak width of digits to create more fitting labels (Thanx Emmanuel Quevillon!)
* better text for labels (alignment and tweaks) (Thanx Emmanuel Quevillon!)
2008-03-30 v0.22 Tels 127 tests
* require Graph::Easy v0.62

2006-09-03 v0.20 Tels 89 tests
* require Graph::Easy v0.47
* fix invalid output on multi-line aligned labels
* fix alignment of labels on loops and vertical edges (text-align takes
"start" or "end", not "left" or "right" - duh!)
* correct the placement of multi-line node labels, especially when
using \r, \l or \c instead of \n
* fix warning and missing arrows when using edge { arrow-style: open; }

+ don't include "stroke-linecap: round" for diamon shapes
+ scale the dasharray according to stroke-width
* remove the workaround for Firefox bug with links:
+ it works now in the latest Firefox, so upgrade!
+ In the newest Firefox, it spawned a second new window
2006-04-17 v0.18 Tels 87 tests
* require Graph::Easy v0.44

* don't draw borders on Group::Cells

* close the hole in open arrows on bold/broad/wide edges
* edge corners no longer have holes
* close the gaps on edges with style double
* fix the fontsize (was missing a "px") and also use 16 as the base vs. 14
This makes the text independed from the user setting in the browser, and
also increases it to be more readable.
* 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
* render selfloops with paths
* don't render invisible edges
* a set background on edge cells did have a stray border
* edge labels have a 80% font-size as default
* only add 0.5EM (currently 8 pixels) as padding around the graph (was 14)
* add a few characters to make the _text_length() calculation more accurate
* a Node::Empty should not be rendered
* font is really font-family in CSS section
* support point-shaped nodes with point-style: invisible
2006-01-29 v0.17 Tels 73 tests
* use Module::Install (and bundle it)

* add support for:
+ invisible edges
+ nodes with "shape: img" (Thanx to Jeff Schiller for pointing out
svg:image!)
* add an onclick-handler to links to force them to open in the current
window/tab - work around bug in FF 1.5 (Thanx Jeff Schiller again!)
* 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
* forgot to limit precision on some edge-line coordinates
2005-12-18 v0.15 Tels 72 tests
* require Graph::Easy v0.36
* fix edge crossings with different widths (wide vs. broad etc)
* add rendering of edge joints
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)

* correct node-sizes to accomodate border-width
* shorten edge-pieces with labels a bit
* implement a crude version of _text_length(), returning the text length
in pixels depending on EM and the string content ("WW" vs. "ii"). This
stops nodes from being overly broad with lots of padding.
* don't generate invalid SVG on labels/node names with "--", "&", "<" or ">"
* limit precision on edge-lines and arrows to 2 digits (instead of 4)
2005-11-06 v0.11 Tels 56 tests

mouseover titles
* nodes with shape "none" result no longer in invalid SVG
* only include the actually used defitinons, that shortens the output,
especially for small graphs

shortens the output a bit
* shorten output by grouping multiple lines of an edge together
* text in (invert)-triangle etc nodes is better displaced to fit better
* better rendering of multi-line labels on edges
* support multi-line labels on nodes (correct hight, multi-line text)
