    Bump pycairo requirement to 1.11.1
    
    This requires pycairo from https://pycairo.readthedocs.io/en/latest/
    (already updated/included in JHBuild)
    
    For more info on the upstream change see:
        https://lists.cairographics.org/archives/cairo/2017-April/027919.html
        https://mail.gnome.org/archives/desktop-devel-list/2017-April/msg00065.html
    
    This will enable cairo.Region support for all setups and Python versions as well
    as make moving to Python 3 easier for applications since all APIs provided
    under Python 2 are available there as well now.
