An SVG file that an <image> links to was parsed with usvg's from_data_nested, which drops every href to a file, so a PNG or JPEG that the SVG file linked to disappeared without a placeholder or a warning. The files a linked SVG file's own <image> elements link to are now read the way the imported SVG's links are, relative paths from that file's folder: a raster stays linked, an SVG file imports as vector art, and one that can't be read (missing, or refused by the reader) gets the placeholder stretched to its box, its link and a warning. The same href in SVG files of two folders names two files. A link that leads back to an SVG file showing it gets the placeholder and a warning. Reading the links of linked SVG files stops at the element depth cap and at 1,024 reads and 512 MB of text per import, the same limits decoded nested SVG images have, counted separately from them. An SVG data URL still reads no file links, having no folder of its own. SVG 2 tells a viewer to ignore external references in an SVG shown by <image>; reading them on import is VectorCraft's own rule.
