Nitpicking:

"Dithering" in raster graphics is emulation of color resolution at the
expense of space resolution. Multiple coarsly colored pixels together
create the impression of a finer color tone. A certain random aspect is
added to prevent unwanted patters.

The fuzzy lines are rather the opposite. They use surplus color
resolution to emulate ibetter spacial resolution. Over here the usual
term is "Anti-aliasing".

I get a suspiciously high share of german language results when
searching this term in the web. But "Computer Grapics" by Foley, Van Dam,
Feiner, Hughes of 1990 has a dozen occurences in its Index.


Have a nice day :)
