2017-09-12	ray: don't assume x_alpha is 0 at begin or y_step	Vito Caputo
	Currently fragments always start at the left edge of the frame, but when switching to a tiling fragmenter this is no longer true and causes visible errors.
2017-05-27	ray: normalize direction missed in 28d8022	Vito Caputo
	Need to normalize the direction when we step the y axis and @ start.
2017-05-26	ray: s/nlerp/lerp/ where normalize is unnecessary	Vito Caputo
	It's only necessary to normalize the direction stored vector in x_step(), the rest can simply be linearly interpolated which saves some divides.
2017-01-18	*: move source into src/ subdir	Vito Caputo
	Restoring some organizational sanity since adopting autotools.
