Class Members
SVGDocument *	document = nullptr	Document to rasterize. Must outlive the atlas call; null entries are skipped. Outliving the call is a hard requirement, not a lifetime convenience. A GPU backend keeps each document's resident geometry and bind groups in components on that document's own registry and consumes them when the frame is submitted (see donner/svg/renderer/geode/GeodeResidentPathComponent.h), so a document released before this call returns frees buffers the recorded draws still reference and its tile comes back blank. Callers bounding peak memory must therefore shrink the batch, not shorten a document's lifetime inside one.
Vector2i	originPx = Vector2i::Zero()	Top-left corner of this document's tile, in atlas device pixels.
