Accurate Sprite Quantize about aseprite HOT 4 CLOSED

Currently you can quantize the palette using the "Quantize" button of the Palette Editor (F4) before the RGB -> Indexed conversion. Anyway I think it is not accurately enough when the RGB image contain less than 256 colors.

I was working for the next release in a replacement of the current RGB palette quantization with the one which comes in jpeglib (which is thread-safe, the current one is not thread-safe and is giving problems to generate image previews in the File Open dialog).

Your idea to accurately quantize palettes when "numofcolours < 256" is very good. I'll try to implement it soon.

This feature is implemented in master branch. Anyway there are performance issues. I'll leave this open for 1.0 to review the new quantizer.

Review performance (and bg worker thread/progress bar when quantizing RGB images in File > Open) for v1.1. Actually the UI is completely blocked.

The quantization works ok (now in the palette-with-alpha branch it works for color with alpha too).
