+++ This bug was initially created as a clone of Bug #481075 +++

We need support for subtitle renderes in playbin(2), for example assrender.
Currently we only support parsers that output timestamped text and playbin
internally links it to an overlay element (textoverlay). assrender OTOH takes
subtitle and video input and does the overlaying itself already.

For this it probably makes sense to introduce a subtitle bin, which takes video
and subtitle as input and outputs overlayed video. Internally it would look for
renderers and parsers and handle everything that is needed.
