Backport e8f31164b9

error[E0599]: the method `to_image` exists for mutable reference `&mut [RGB<u8>]`, but its trait bounds were not satisfied

   = help: items from traits can only be used if the trait is implemented and in scope
note: `convert::ToSRGBImage` defines an item `to_image`, perhaps you need to implement it
