set_clip()

bool MayaFlux::Portal::Forma::Layer::set_clip	(	uint32_t	id,
		std::optional< Kinesis::AABB2D >	clip
	)

Confine hit testing of an element to a region, or lift the confinement with std::nullopt.

The clip survives set_bounds, set_contains and Mapped::sync, which rewrite the element's own shape but not where it may be hit.

Returns

True if found.
