Currently working on graph layout stuff outside of inkscape. A couple
of things have flowed to inkscape from that, such as a start on
dia-like connectors in inkscape.
More recently (after the freeze) I've improved the orientation of
markers (arrowheads), continuing David Novalis' work ~a month ago. I
haven't yet tried the test cases that were posted when this was last
discussed, but it gives right-looking[*1] results for all pictures I've
encountered where inkscape was previously giving wrong-looking results.
[*1]: Let's say "conforming-looking". The SVG spec's "half way between
the two angles" rule isn't really what humans want for arrowheads.
Indeed, if a human placed arrows along a line, then they'd probably
_avoid_ placing an arrow directly on a vertex. We know that end-marker
arrows aren't handled well by the spec, especially on a path that
curves sharply towards its end. We could summarise by saying that the
SVG marker spec does fine for circle markers or even squares/diamonds,
but isn't well suited for arrowheads in subjectively-most cases.
Back to the subject of smoother freehand drawing: since we last spoke on
the subject, I have done some cleaning of the code that I had, and I'll
have another look once we've submitted the graph-layout paper we're
