This function has the same argument as the corresponding ggplot2 scale
functions where the index after the aesthetic name is omitted from the function.
E.g. scale_fill1_binned has the same argument as scale_filled_binned.
Where there is multiple fill scales, the index after the aesthetic name
determines which fill scale is modified.
