Yes, I've been using it. I think it works fine for me. (I am using a
patch I submitted to allow overscan mode in addition to letterbox, but

I do recall some programming error I once made where the
SetRenderLogicalSize caused everything to be restricted to the
top-left corner only on Android, but I forgot what caused that.
