Detailed Description

template<typename InvalidateCallback>
class donner::svg::SVGElement::ScopedMutation< InvalidateCallback >

Scoped mutation helper that runs cleanup before committing the mutation revision.

This is intended for element setters that need to invalidate cached computed state after the raw SVG attribute component is changed. The callback runs while the write access from the mutation batch is still active, and before the coalesced mutation revision is committed.
