> `gtk+.inc` `DEPENDS` on `cups` [1]. Is this converted to `cups-native` for `gtk+-native`?

Yes.
see native.bbclass, around line 118:

        for dep in deps:
            if dep.endswith("-cross"):
                newdeps.append(dep.replace("-cross", "-native"))
            elif not dep.endswith("-native"):

                newdeps.append(dep + "-native")
            else:
                newdeps.append(dep)
