Use lossless for Q0 The commit changes the coding mode to lossless whenever the lowest quantizer is choosen. As expected, test results showed no difference for cif and std-hd set where Q0 is rarely used. For yt and yt-hd set, Q0 is used for a number of clips, where this commit helped a lot in the high end. Average over all clips in the sets: yt: 2.391% 1.017% 1.066% hd: 1.937% .764% .787% Change-Id: I9fa9df8646fd70cb09ffe9e4202b86b67da16765
