The `drawtext` filter currently does not allow fading in or fading out of
text. It'd be a useful feature to have, but at the moment, I think this
can only be achieved by rendering ASS effects, pre-generating the subtitle
text with ImageMagick (or something similar), or a super complex `blend`
filter.
I could imagine that this is easily implemented with two additional
options:
* fade in duration
* fade out duration
