	RingCanvas (fl::span< RGBf > px)

void	clear ()

void	fill (const RGBf &color, float gain)
	Add the same colour to every pixel.

void	lobe (float pos, float sigma, const RGBf &color, float gain)
	Add a smooth lobe centred at pos (turns) with half-width sigma (turns).

void	pixel (int i, const RGBf &color, float gain)
	Add to one pixel, index wrapped.

float	posOf (int i) const
	Position of pixel i in turns.

void	ring (float origin, float radius, float sigma, const RGBf &color, float gain)
	Add a band at distance radius (turns, 0..0.5) from origin, on both sides of it at once: an expanding pulse ring.
