    Found-by: ami_stuff
    Fixes out of array write in jpeg2000 decoding
    Found-by: ami_stuff
    Fix order of align and pixel size multiplication.
    Fixes out of array accesses in g2m4
    Found-by: ami_stuff
    avcodec/pngdsp: fix (un)signed type in end comparission
    Fixes out of array writes in png decoding

When the tyrant has disposed of foreign enemies by conquest or treaty, and

some war or other, in order that the people may require a leader. -- Plato
