I would strongly recommend making the text rendering to a frame
into a library, or at least easily modifiable into a library.  It's
a pretty generic operation that could be used in videotestsrc,
subtitle overlay, channel number/name overlay, title generation,
a crawler overlay (text crawling on the bottom of the screen), etc.
