When dealing with multi-tile graphics that don't need to have a physical map presence, what's the most convenient and efficient way to go about organizing icons, states, etc.? For a current project I've split each 32x32 chunk of each graphic into its own icon, so that I can set up an overlay spread using pixel x/y when a multi-tile atom is created and then not have to worry about animating individual chunks. The only problem is that it's a pain feeding everything into the appropriate icon files, and I haven't even gone into diagonals yet. Any other methods anyone's fond of?
