gEDA-user: gschem with b-spline paths and filled sections

[Peter Clifton <pcjc2@xxxxxxxxx>]

Just thought I'd share a couple of screen-shots of a feature hopefully
targeted for gEDA 1.6.0, support for closed / filled polygons.

Since its simple to do so with cairo, I've implemented this a an
arbitrary SVG type path string. Code-reuse from librsvg (LGPL) made this
a more approachable task.

Screen-shots:

At the moment, the code allows modify existing paths from within gschem
by dragging the control points, but you can't yet create new paths,
add / remove nodes or change node-types.

At the very least, we could hope to support reading and rendering
polygons / closed arbitrary paths for gEDA 1.6.0, so if anyone is keen,
the stock libraries can be improved with this pretty'fication. I already
made a stab at the bipolar transistors.

Best wishes,
