on_resize()

void MayaFlux::Portal::Forma::Context::on_resize	(	uint32_t	id,
		ResizeFn	fn
	)

Called on every window resize.

Per-element like the other callbacks, so more than one bound id (e.g. several pixel-anchored TextFields on the same Context) can each react independently. Cleared by unbind(id) same as every other callback.

Hit-test-driven placement (to_ndc() at event time) already tracks resize for free; this is for callers anchored by a fixed pixel rect via to_ndc_rect(), which must be recomputed explicitly when the window's dimensions change.

Parameters

id	Element id to bind to.
fn	Callback receiving the new (width, height).
