Description Sven Gothel 2015-03-20 02:37:55 CET 
RandR 1.3 XRRSetCrtcConfig related:

- Our X11RandR13 does not set the new screen size via XRRSetScreenSize(..)

- Our X11RandR13 does not propagate RRScreenChangeNotify events
  via XRRUpdateConfiguration(event).
  Hence reported virtual desktop size is wrong.

- Our X11RandR13 shall disable the CRTC before XRRSetCrtcConfig(..)
  to avoid invalid configuration (see spec)!

RandR 1.3 General:

- We shall use unique id named instead of unstable index 
  for modes and CRTC.
  This allows proper identification even for 'swizzled' devices.
