center logo position
we have a request from one of our customers that requires their logo to be placed over the center of the video (even in fullscreen mode).
I cannot find a way to do this with the customization API. currently the only options are 'top-left', 'top-right', 'bottom-left', 'bottom-right'.
Please consider adding 'center' as an option. Also, perhaps: 'center-left', 'center-right', 'top-center', 'bottom-center'.
I don't think adding these would break any existing client code.
