That's not the intended effect though, what we really want is a black outline
(and additionally the shadow).

For normal subtitles all this should be no problem btw, only for timeoverlay
and clockoverlay or anything else that has text changes very often.

As suggested elsewhere the solution for timeoverlay/clockoverlay would be to
cache the few characters a single time (whenever the font/etc changes) and then
only copy them onto the buffer. Not sure how to do it properly though,
especially the correct spacing of characters. Any ideas?

Also the way the pango plugin works needs to be changed for this
