Each layer can have its own colour used when show-out-line-only is on. This screenshot showing the layer dialog has four toggle buttons for each layer: screen visibility printing visibility (probably including visibility in exported bitmaps) lockedness and a 'show outline only' option. The import/export code is written in Python (see /usr/lib/ske* /Plugins/Filters/*.py), so should be easy enough to adapt to SVG, or we could invoke skencil/skconvert to do the import/export as we do with sk_input.inx. Has some import/export vector file formats that Inkscape lacks (cgm, cmx, fig).(I believe Inkscape honours masking/clipping directives in SVG files, but has no user interface for this unless you count the boolean operations.) Claims to support masking I haven't looked at its interface.'Conical gradients' as well as the linear & radial gradients supported by SVG/ Inkscape.(Inkscape has SVG text-on-path, which I think only allows rotation rather than skew.) (However, I think someone was saying that Inkscape allowed better editing of the path or text afterwards.) Text along path, with choice between rotation or vertical skew of glyphs.Bézier curves, rectangles and ellipses can be used as guides.About the only scriptable free-software vector graphics program.
