    compositor: Fix check to clip beneath the window
    
    We want to clip it away if 1) The window is fully opaque or
    2) If it's translucent but has a frame (as explained in the comment
    above). The code didn't quite match and we were only applying it on
    case #2.
    
    Case #1 is far more common, and saves us from pushing some drawing
    that we know will be covered in the end.
