This change adds support for rendering static SVG images using the `resvg` crate, allowing svg sources in the `img` tag and in CSS `background` and `content` properties. There are some limitations in using resvg: 1. There is no support for animations or interactivity as these would require implementing the full DOM layer of SVG specification. 2. Only system fonts can be used for text rendering. There is some mechanism to provide a custom font resolver to usvg, but that is not explored in this change. 3. resvg's handling of certain edge cases involving lack of explicit `width` and `height` on the root svg element deviates from what the specification expects from browsers. For example, resvg uses the values in `viewBox` to derive the missing width or height dimension, but without scaling that dimension to preserve the aspect ratio. It also doesn't allow overriding this behavior.
