  Constant Colors:
    - 220, 160, 32, 255
    - 255, 255, 255, 200

  Color Registers:

  Steps:
    1: RGB = (lerp from (128, 128, 128) to (255, 255, 255) using (tex #4 RGB))
         A = 0
    2: RGB = (tex #1 RGB)
         A = (tex #1 A)
    3: RGB = (lerp from (prev. RGB) to (tex #3 RGB) using (200, 200, 200))
         A = ((tex #3 A) * (prev. A))
    4: RGB = (prev. RGB)
         A = (prev. A)
    5: RGB = ((220, 160, 32) * (tex #4 RGB)), then add (prev. RGB)
         A = (prev. A)
