 ==== Mode 4/5: U/V Offset ====
-This mode can be used to scroll U and V independently from each other. It has four float parameters. The offset calculation for these modes is unknown; however, the same code is used for both modes, with the only difference being whether the calculated offset is applied to U or V.
