Usually it started as "X-only" and then code started to use it and in
order not to have to fix it other backends also used "x-" when
implementing the corresponding feature.

But this is wrong and should be fixedm and has been fixed in several
cases (e.g. most of the functions that start with "display-").

Yes, maybe it should be fixes wholesale as well, but at least let's not
make things worse than they already are.

Indeed.  And notice that there's `color-defined-p' as well, which is the
one that should be used.
