Andreas Cadhalpun ae6fd7300b msrledec: use signed pixel_ptr in msrle_decode_pal4 This fixes segmentation faults, when pic->linesize[0] is negative. In that case 'line * pic->linesize[0] + pixel_ptr' is treated as unsigned and wraps around. This reverts commit `7d78a964`. The problem was introduced in commit `f7e1367f`, which should obsolete that commit.
