[Inkscape-devel] Powerstroke rounded joins

Hi all, After busting my brain for two evenings, I've succeeded in creating properly rounded joins for powerstroked paths... The quick explanation: - for constant stroke width paths: looks like SVG rounded joins (circular arc) - for non-constant width paths, it is not possible to round with a circle and keep the curve smooth (tangents will not match). So the rounding is done with an elliptical arc, for which the tangents *do* match. There are many possible ellipses, and I decided for the one with minimum eccentricity. This converges to a circle for constant stroke width.

Please test and tell me if it is bugged. (bzr rev 11111)
