The svg crate's new CSS writer (css_rules) gives the CSS web pages style objects
with: rectangles and ellipses as background-color / linear-/radial-gradient(),
border and border-radius; type as font, color, spacing and alignment; shadows,
glows and blur as box-shadow, text-shadow and filter. It shares SVG export's
declarations (transparency, fonts, type spacing, colours, gradient stops), which
moved into svg/src/css.rs. Options: units, absolute position, width and height,
unnamed objects, rasterize unsupported art (as a PNG background-image).
Commands css.selection, css.generate and css.export; UI commands css.copy and
css.exportFile; the CSS Properties panel with a highlighted code view.
