[Xcb] xcb_randr

[Michael Grunditz]

Hi

I am trying to understand how xcb_randr works , I am interested to use
it for changing resolution. I have studied the headers and the
"xrandr" program. My guess is that I want to use
 xcb_randr_set_screen_size.

Do I need something more than that , if I use
xcb_randr_set_screen_size , nothing happens.  xcb_randr_query_version
returns 1.2, so the server supports randr.
