I would also like to know why there's no float version (it shouldn't be 
hard adding the function though).

Also, is there a use case for the 8-bit data versions? Only possible 
idea I've come up with is that you can use it directly as a WebGL 
texture source or something, but I'd still rather see a high resolution 
version in the first place (you can do the conversion to 8-bit yourself, 
but the other way around is impossible).
