    magnifier: Apply color inversion to crosshairs/pointer
    
    It is somewhat unexpected that crosshair color and pointer cursor colors
    remain the same across changes in color inversion settings, and may lead
    to contrast issues. Apply the effect on the common container, so it
    applies to these all.
