    Don't check for soft buttons if a button is already down
    
    Moving into a different soft button's area during drag-n-drop would trigger
    a click of that button.
    
    We only have the current button state and we mess with it, so the conditions
    for a possible clickpad soft-button event are:
    - hw->left is down now
    - none of left|right|middle were down before. since we change hw->left to
      hw->right/left we need to check all three
    
    If hw->left is down but one of the other buttons was already down, copy that
    button state and continue.
