fixed a rounding bug thing in the X1 Filter
changed the X1 Filter slightly to make flat blocks look like in the 9tap lpf minor change to the -pp numbers & added decimal numbers in comments new experimental horizontal deblocking filter Originally committed as revision 2180 to svn://svn.mplayerhq.hu/mplayer/trunk/postproc
