    textview: revert the code preventing initial backwards selection
    
    With the handles being invariably set to the min/max selection positions,
    it's no longer necessary to keep this invariant when starting a selection.
    
    Note that dragging from the text handles themselves will still disallow
    both handles from crossing.
