Restored image subtitle rendering functionality
Created by: TobbeMobiTV
The "SMPTE-TT" backgrounImage subtitling for non-HTML rendering got broken in PR #705.
It has now been repaired and tested with a prepared content for both html and non-html rendering.
However, both in its former and present state there are a number of issues with this implementation compared to SMPTE-TT.
- It is on the
<p>
level instead of<div>
level. (SMPTE-TT only supports background images for full duration). - imagetype should be imageType.
- The region parameters for placement on screen are completely neglected.
