  - Merge "Fix distance check for minimum touch target" into androidx-main
  - Fix distance check for minimum touch target
    
    Fixes: 223588290
    
    Previously, the minimum distance in the horizontal or vertical
    direction from the layout bounds was used to determine the
    closest touch target when in the minimum touch target area.
    This causes a strange effect where you can be right next to
    one layout and farther from another layout and the farther
    one could be selected.
    
    This CL uses the actual distance from the layout bounds
    to determine which is closer rather than treating each
    axis separately.
