Refactor rgb() and hsl() to reduce repetition and ensure that they always
return plain CSS function calls with the correct names.
Fix a redirect that didn't get the extra text about renaming its plain CSS.
Support rgb(var(--foo) / 0.5) and hsl(var(--foo) / 0.5), since the
variable could expand to a list of arguments.
Remove the hsl($color, $alpha) overload, since it redirects to an hsla()
overload that doesn't exist.
Ensure that function redirects always return plain CSS functions with the same name as that written by the user.
Specify behavior for special variable functions, which may expand into multiple arguments.
Specify behavior for special number functions which are converted into strings
due to /.
