Return elements to be added to the <defs> section of the canvases SVG context. This can be used to define SVG content (e.g. patterns & masks) that can be referred to by ID from svg elements returned by component.

Each def should have a unique key. If multiple defs from different shapes all have the same key, only one will be used.
