D17982: [kcmkwin/kwindecoration] Fix visuals of KCM decorations' buttons tab

vpilo added a comment.


  @davidedmundson 
  I could not use TextMetrics; it was not accessible outside of the Delegate and useless when associated to the dragHint (that's why I just used `dragHint.implicitHeight`). Did you mean something else?
  
  Re: cellHeight, the easiest way I found to have it look decent is letting QML do the job - I tried A LOT of different ways, something always got messed up.
  This qml is... delicate.
