[IMPOSSIBLE] Custom info overlay in play/qr

[Marsu42]

The Canon overlay in play/qr modes is cluttering the view - the font is larger than necessary, and they display information at least I don't care about. At the same time, switching the overlay off completely isn't an option since I require *some* pieces of information.

Would it be possible to print a customizable ML info line instead of Canon - or is some of the information Canon has (like Av/Tv) inaccessible to ML in play mode? Having this feature would also be useful when (and if) ML file tagging is added.

Edit: Marked this as impossible unless someone is willing to to the re alex described below.

In QR you may have access to exposure settings or file number (or maybe not if you use auto-anything; I wouldn't rely on this).

In playback mode you only have access to the YUV buffer (anything else requires reverse engineering and is likely to be camera-specific).
