simple OSD pop-up support for plug-ins?

[johnsonx42]

I suppose this request is as old as PVRX2, but any chance of getting a function call for plugins to pop-up a line of text over video? I'd really love to implement CallerID, but the old CallerID plugin (or any potential new plugin) can't be resurrected until there's a way to do a pop-up. Nothing fancy is needed, just a single line hard-coded to the top (or bottom) of the screen will do to get things started.
