SvgDrawing class

A parsed, dependency-free rendering of a small SVG subset.

Supported subset

• Structure: <svg> (viewBox, width/height), <g>, <defs>, <clipPath>, <use>-free.
• Shapes: <path>, <rect> (including rx/ry), <circle>, <ellipse>, <polygon>.
• Paint: fill (#rgb, #rgba, #rrggbb, #rrggbbaa, rgb(), rgba(), a handful of named colors, none), fill-opacity, fill-rule, opacity, and the same properties written inside a style="…" attribute.
• Geometry: transform (matrix, translate, scale, rotate, skewX, skewY) and clip-path="url(#id)".

Everything else — strokes, gradients, filters, text, images, masks, objectBoundingBox clip units — is ignored by design. Group opacity is multiplied into descendant fills rather than composited through a layer, which is exact for non-overlapping flat artwork.

This exists so package:device_preview can draw device bodies with zero dependencies; it is not a general purpose SVG renderer.
