I have a question regarding retina display graphics. I understand you are suppose to double up the dimension of an actor ( ex. 256x256 becomes 512x512 ) My confusion is the following, if that rule is followed, would every graphics have to be square? is an "actor" different from a "graphic"? Looking at a graphic I just made, it tells me that its 556x307. Its wider than taller. how do i make it so that its divisible by 2? Im sure I am missing the logic behind this any help would be appreciated. Thanks in advance for the help.
