    spice-widget: Fix invalidate region in case of image is scaled
    
    In case the drawing on the screen is scaled the scaling required to
    invalidate a slightly bigger region.
    This is due to the interpolation done during the resize.
    So if scaling is performed invalidate also the adjacent pixels.
    
    This fixes https://gitlab.freedesktop.org/spice/spice-gtk/issues/19.
