What's the status of this patch? May I ask if you have plans to continue with it? Speaking of multiple AF windows --- I originally thought we could just have multiple selection targets for them. I'm not sure which one would be better; multiple selection targets or another field telling the window ID. In case of the former we'd leave a largish gap for additional window IDs. I think I'm leaning towards using one reserved field for the purpose. Another question I had was that which of the selection rectangles would the AF rectangle be related to? Is it the compose bounds rectangle, or the crop bounds rectangle, for example? I thought it might make sense to use another field to tell that, since I think which one this really is related to is purely hardware specific. What do you think?
