This was a tool I wrote to speed up the art production pipeline. The game engine handled all of its assets through script, and entering several hundred textures in by hand can be very time consuming. You also had to specify the bit depth, which could really slow you down. Draw order was also partially controlled by the order you listed the textures in so you want all alpha textures at the end. This tool automatically generates a new header with accurate bit depths and draw order placement at the click of a button.
