Neat. This introduced some bug, however.

In window mode there is no performance difference, however fullscreen
mode (when mplayer is run with -fs) renders subtitles in the wrong
place, as if "ass-use-margins" option is active. What's even more
strange is that if I switch to window then back to fullscreen, subtitles
start appear on correct place (on video, not on black bars) and do that
from that point till the end of video.
