Block video encoding test

+

+ Test work for a video encoding using Atari 800-family GTIA grayscale mode on top of text cells. + This allows a "block dictionary" of 128 2x8-pixel blocks on an 80x160 grayscale image, + at cost of 1840 bytes per full frame or 800 bytes to reuse previous blocks. +

+ +

+ Currently just converts to grayscale and counts up unique blocks. + Next step: decimate if > 128 unique blocks per image, and combine + the most similar blocks in the output. +
