** Description changed:

  == SRU Justification ==
  [Impact]
  Double tap desktop icons on a touchscreen barely works.
  
  [Fix]
  Because tapping isn't as precise as clicking, ignore the double click 
distance as long as the icon is tapped.
  
  [Test]
  Roughly double tap the desktop icon and nothing happens.
  After applying the fix, double tap can 100% open the app or directory.
+ [racb] Since single click code is also being adjusted, please test that 
single clicking behaviour has not changed.
  
  [Where problems could occur]
  If the new code throws any exception, clicking can also be affected.
  
  == Original Bug Report ==
  Double-clicks touchscreen on HiDPI system, sometime it will not be detected.
  Here is a related patch on upstream
