    WindowManager: scale windows to their monitor's corner on minimize
    
    We previously scaled windows to (primary.x, 0), which is wrong if the
    primary monitor is not at y == 0. At the same time, change the policy
    to pick the hot corner on the monitor the window is on, because that's
    closest to where it will appear in the overview.
