I'm just hacking through the first few chapters of James Newton's
book and he mentions two different dither algorithms for 16 bit color
that are undoc'd and may or may not work.
The params are [#dither:1215] and [#dither:1969] -- the latter is
according to James a higher-quality one.
However he also points out that there is no RGB ( 255, 255, 255 ) in
16-bit color; the highest white value is actually rgb ( 248, 248, 248
).
I guess the thing to do is try a plain vanilla dither from 32 to 16
in different situations and see if you *ever* get a conversion to
solid white. I bet you don't based on what I've been discovering...
