Xpra: Ticket #992: FLIF - Free Lossless Image Format

flif.info claims: FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG and lossless JPEG2000 in terms of compression ratio

What we don't know is if the CPU usage is comparable to those formats. progressive decoding could be useful for us: the encoding is done in multiple passes, we could send the partial data after each pass and cancel later passes if a new refresh comes in.
