The new `svg-dc%' drawing context is similar to `post-script-dc%',
but it generates SVG output.
All drawing contexts, including `post-script-dc%' support smoothing
modes, and the default is 'unsmoothed even for `post-script-dc%' ---
which means that PostScript drawing is aligned and pen widths are
truncated to integer sizes by default. Drawing at pen size 0 no longer
triggers ``hairline'' mode, but instead just uses a 1/4-width pen
when in 'smoothed mode.
