Ah, that's one of my earlier documentations I made. The intro editing/injection was one of my first experiments with C stuffs, which later ended up getting thrown into CrystalDust because wynaut. After I got it figured out, C was surprisingly easy to integrate and makes for an amazingly easy method for doing fancy editing stuffs (especially with graphics and math intensive stuff). Was a lifesaver for integrating the color mixing in Wizard, although ASM could have made it much more efficient. Might port it to ASM eventually, but for now it works so whatever.
