Is it possible to display a text overlay on top of an roVideoScreen?
The DesignGuidelines.pdf and MockUpTool.pptx documents shows a wireframe of a text overlay screen with "[video or photo stream]" in the middle of it.
However, the Component Reference guide seems to only describe how to create a text overlay on top of a slide show (where it describes the use of TextOverlayUL, TextOverlayUR, and TextOverlayBody, it is all in the context of roSlideShow).
And I see no other mention of Text Overlays in the Component Reference besides the above.
So is it even possible to create a text overlay on an roVideoScreen (as the Design and Mockup docs indicate)?
