Somewhat confusing commit message or I'm just being dense, your choice.

Although I think that @info data for graphics devices could be moved
into patch4 since that's where it makes more sense (eventually at least).

Logic seems right vis-a-vis replacing a bool with a flag properly. I
don't get the name and comment, but I'm not sure I could name it better.
The called function with the @all flag only processes when @all == false
as I'm reading things. Anyway, if someone has a better idea, then they
should speak up before you push!
