frame50 as benchmark:
	+ raw binary is 1024 bytes (2048 pixels)

hand-crafted:
	+ 25e0 - 24d8 = 264 bytes

todo, compressed:
	+ ???


Before VLIN_ADD (at frame 130):		23488 bytes
After:					23330 bytes (not worth it?)
Bunch more optimizations		23164 bytes


7680 bytes: try1: all plots, even zeros (4 bytes each pixel)
4537 bytes: try2: all plots, don't write black pixels
3701 bytes: try3: only do color if it changes
2568 bytes: try4: use compact form (only change type if changed)
1194 bytes: try5: use hlin (essentially RLE)
 906 bytes: try6: sort by color first
 628 bytes: try7: initial use boxes
 526 bytes: try8: boxes that optimize to HLIN/VLIN/PLOT
 522 bytes: try9: optimize HLIN to HLIN_ADD variants
 506 bytes: try10: sort types per color
 498 bytes: try11: sort HLIN by Y1
 431 bytes: try12: with don't cares
 336 bytes: try13: sort colors by popularity
 299 bytes: try14: shrink the window for finding colors to only include colors
 299 bytes: try15: sort BOX (not expected to be smaller)
 293 bytes: try16: add BOX_ADD types
 293 bytes: try17: permutate the top 4 colors to see if it improves

TODO:
	Only use don't care result if not wider than max X or longer than
		max Y
	sort BOX and do optimizations like HLIN


	Try all color combos?
	K-permutations.  For K=16 it's literally billions+?
	Maybe try just top 4?  Only 24 combos then?

	MOVE PLOTS one line before HLIN?
