(reserved for 256-color to 16-color dither from newtrix demo)

https://www.mobileread.com/forums/sho...d.php?t=176802

This code in particular will be a good starting point for a "generic" dither routine to be used with any (native mode) app. You feed it a 256-color framebuffer, which does not need to be pre-dithered (unlike real framebuffer content on a K5), and this routine converts it to whatever is needed to be in the real framebuffer of any eink kindle model in any boot mode (probably needs updates to work on PW or PW2).

This code uses dither tables, so I will want to convert that to logical formulas as shown in the first post in this thread.
