Øyvind Kolås	3e6016622e	swscale: add two spatially stable dithering methods Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results	11 years ago

Reimar Döffinger	4fab08c94f	Optimize pure C unscaled yuv2rgb. Aligning the tables reduces the amount of code generated on e.g. ARM as the offset constant then has few enough set bits so it can be encoded inside a single instruction instead of 2. Ideally all should be declared aligned, but the DECLARE_ALIGNED macros does not work with pointer tables, thus also reordered the tables.

Michael Niedermayer	1e0e193240	sws: add dither enum This allows specifying more dither algorithms without using up flags and without ambiguities. Also initialize the new field based on the flags and use it. Note, improving the logic of the checks is left to subsequent commits, this here only switches from flags to enum.
