Pascal Massimino f82cb06afb optimize palette ordering ... We compact the palette by weighted distance, favoring the green channel. Average gain on paletted file is ~0.5%, with gain up to 6-7% on some favorable cases. Encoding speed is unaffected. Disabled for alpha (or any single-channel input) Also: always use quality=20 for EncodePalette() since it doesn't make any real difference.
