This would not change the amount of memory we would need to allocate,
we would simply be buffering the entire slice in memory before
inverting it in the decoder. While it would be faster than doing it
for an entire image at a time, the memory requirement makes this
suboptimal.
I second that, currently it is possible to just keep in fast memory 2
lines, and it is an advantage, especially when we need to process 8K
content.
Also, here we talk about an update of FFV1, not FFV2 or any new format,
keeping the process simple and based on what already exists is IMO more
important that getting the "best" (speed? compression ratio? or less
complexity).
