Fully passes only on desktop and ES3 (Mesa), expecting minor differences onother GPUs. ES2 is slightly broken and needs fixing; doesn't even compile on WebGL 1 and causes a serious GPU stall on WebGL 2 -- in both causes caused by the unbounded nested loops. Rendering doesn't work on WebGL 1 at the moment, since luminance formats are not renderable. And for a RGBA output format I would need some utility to get rid of the extra channels in order to pass the comparison. Lots of work to do here.pull/289/head
