    actor: improve rounding in get_allocation_geometry
    
    Instead of relying on C to round the floating point allocation to
    integers by flooring the values we now use CLUTTER_NEARBYINT to round
    the allocation's position and size to the nearest integers instead. Using
    floor leads to rather unstable rounding for the width and height when
    there may be tiny fluctuations in the floating point width/height.
