Feature request: rescale.AsIs method

[teunbrand]

In ggplot2 we're considering to let AsIs vectors be unresponsive to scales in tidyverse/ggplot2#5477.
What would work really well for that PR, is if {scales} would define a recale method for AsIs objects that returns input unaltered.

My proposal is simply the following:

rescale.AsIs <- function(x, to, from, ...) {
  x
}

Currently, no such method exists, so we're unlikely to be harming any existing code out there:

scales::rescale(I(1:3))
#> Error in UseMethod("rescale"): no applicable method for 'rescale' applied to an object of class "AsIs"

Sounds good to me. Would you like to create a PR?

Yes, I'll prepare one later today.
