Subject: [PATCH 1/1] randr: make RROutputChanged change the main protocol
 screen not the gpu screen

We only set changes on the main protocol screen as, for example
in RRSetChanged() and RRTellChanged(), therefore we should follow
the same logic when reporting that an output changed in
RROutputChanged().

This means that RRTellChanged() will then update the relevant
timestamps also when events come from gpu screens.
