[Kde-hardware-devel] KScreen: Do preferredMode right

[Alex Fiestas]

So far we are exposing only one preferred mode in the Config api even though 
in really there are more than one preferred mode and we should expose that.

Besides, while fixing the XRandR backend to return only the best suitable 
preferred mode, I realize that this job should be done by the frontend, or 
rather not by the backend (check the best suitable preferred mode).

As a result of this, I have pushed a branch called preferredDoneRight where:

-Output::setPreferredMode has been deleted
-Output::setPreferredModes(Qlist<int> modes) has been added
-Backends ported

This way, we stay compatible while doing it right :p

I have pushed the same branch to kscreen and tested it.


Branch name: preferredDoneRight
