// Tests that two SubRenderPasses in the same main pass each acquire a unique
// userPassData slot. The cube on Layer0 should appear red (SubPass1 override)
// and the sphere on Layer1 should appear blue (SubPass2 override).
// If the index fix is broken both would use the same slot and one color would
// overwrite the other.
