scroll_by()

void MayaFlux::Portal::Forma::Scrollable::scroll_by	(	Layer &	layer,
		glm::vec2	delta
	)

Apply a scroll delta and reflow every tracked element.

The input-agnostic core: place() wires wheel input to this by default, but any other trigger can call it directly with its own delta - nothing here assumes the source.

Parameters

layer	Layer the viewport and every tracked element were registered on.
delta	Content-space scroll delta, added to the current offset and clamped to scroll->content_bounds.

    reflow(*scroll, *offset, *m_tracked, layer, m_indicator.get());
