Can you clarify, what does it mean "wrong", this why we cannot use it or 
what? If it is wrong then we can fix it, if it is correct why we cannot 
use it? It should be the same as getNativeScale(), because it is based 
on getNativeScale(), but unlike getNativeScale it is a public API which 
is unrelated to X11.
