commit 4cfa4615f79f64062e5e771cd45dd7048f48b4f6
Author: Michel Dänzer <michel.daenzer at amd.com>

    Use drmmode_crtc_scanout_* helpers for RandR 1.4 scanout pixmaps
    
    This should allow using multiple CRTCs via RandR 1.4 even with xserver
    < 1.17. It also simplifies the code a little, and paves the way for
    following changes.
