title: Make WPF window draggable, no matter what element is clicked
body: <p>My question is 2 fold, and I am hoping there are easier solutions to both provided by <strong>WPF</strong> rather than the standard solutions from WinForms (which Christophe Geers provided, before I've made this clarification).</p>
  
  <p>First, is there a way to make Window draggable without capturing and processing mouse-click+drag events? I mean the window is draggable by the title bar, but if I set a window not to have one and still want to be able to drag it, is there a way to just re-direct the events somehow to whatever handles the title bar dragging?</p>
  
  <p>Second, is there a way to apply an event handler to all elements in the window? As in, make the window draggable no matter which element the user click+drags. Obviously without adding the handler manually, to every single element. Just do it once somewhere?</p>
