Comment 37 for bug 612377

After a cursory look at the code, it seems like libjpeg-turbo may want to borrow Mozilla's enhancements, where applicable. In particular, the use of static tables in choice areas like RGB->YUV conversion is likely to improve our performance as well.

Also, there is some of the code which is going to conflict, because your version already has some SIMD acceleration. I think that most of it could be replaced with ours, but the areas in which you use SSE2 would probably need to be benchmarked against our version to see which is faster (integer IDCT, for instance.)
