db6e007c44 Back-port code from jpeg-8 that removes unpopulated (and unneeded) tables for AC and DC coefficients when generating progressive JPEG files with arithmetic coding. This should make such files bitwise compatible with jpeg-8, barring any other mathematical differences listed in README-turbo.txt. Add regression tests for progressive+arithmetic JPEG files. 2013-11-06 06:50:38 +00:00
