commit d8b764fbd27dc9c8b28386093931b8d38855bd19
Author: Keith Packard <keithp at keithp.com>

    Add RandR 1.3 panning support by supporting the crtc set_origin function
    
    RandR 1.3 panning support can use the regular mode setting interface, but
    that's really slow. Providing set_origin makes it nice and snappy.
