something interesting for subtitles is the 'halo' of the text, like that:
http://avisynth3.unite-video.com/avs_text.png
it is sometimes necessary to have that halo because the text can be
unreadable if the color of background is closed to the one of the text.
I don't know if it is easily doable with evas or not.
