This bug is about adding a complete (or at least more complete) ASS/SSA
renderer to gstreamer, like mplayer has one. ASS is very complex subtitle
format with support for many formatting options, styles and effects.

Other text subtitles don't work "fine" either because of some shortcomings of
the textoverlay plugin:

1) textoverlay can only display one line of text at once. Some subtitle formats
(including ASS) can display more than one line at a time. In that case the
textoverlay plugin would have to handle collision detection, so that the lines
won't overlap.

2) It does not offer nice formatting and styling options. At least being able
to set text color and outline would be nice.

However, for these, a SEPARATE BUG should be opened. This bug here is solely
about ASS/SSA rendering.

For a start, mplayer has the most complete ASS rendering via libass. It should
be possible to use this in gstreamer somehow.
