Add changes from
http://greg.geekmind.org/mplayer/libass-snapshot-20090214.tar.gz * \be filter with [1,2,1] kernel (like vsfilter) * "decimal point" support, e.g. numbers with fractional parts are dealt with correctly * shadow without border * "compromise" fix for transparency + aa * misc fixes: \be and \blur radius and a memory leak * proper compositing of overlapping translucent outlines Originally committed to SVN as r2733.
