SVG import for EffectCraft: .svg files import as footage (rasterised at any scale, so Continuously Rasterize stays sharp) and Layer ▸ Create ▸ Create Shapes from Vector Layer turns them into editable shape layers.

Implemented from the W3C Scalable Vector Graphics (SVG) 1.1 (Second Edition) recommendation (16 August 2011) and the SVG 2 candidate recommendation (4 October 2018) for the parts listed here, plus CSS Color Module Level 3 for colour keywords and functions:

document: svg (width/height, viewBox, preserveAspectRatio), nested svg, g, defs, use (x/y, href / xlink:href), symbol (through use), title/desc/metadata ignored;
shapes: path (all path data commands incl. elliptical arcs), rect (rx/ry), circle, ellipse, line, polyline, polygon;
transform lists (matrix, translate, scale, rotate with centre, skewX, skewY);
painting: fill, fill-rule, fill-opacity, stroke, stroke-width, stroke-linecap, stroke-linejoin, stroke-miterlimit, stroke-dasharray, stroke-dashoffset, stroke-opacity, opacity, display, visibility, color/currentColor;
linearGradient and radialGradient (with fx/fy focal point), gradientUnits, gradientTransform, spreadMethod, href inheritance of stops and attributes;
styling through presentation attributes, the style attribute and <style> sheets with type, class, id and universal selectors (simple selectors and selector lists).

Not supported (ignored): text, images, filters, clip paths, masks, patterns, markers, animation. XML parsing uses roxmltree (MIT/Apache-2.0). Test fixtures are original work (see tests/fixtures/*.attribution).
