D27174: actually draw drag icons in the mouse cursor during drags

  It does.
  
  A drag has a surface
  A surface has a buffer
  A buffer has an offset (or hotspot) to the surface
  
  Qt does set this:         
  qwaylanddnd.cpp:70

I don't think this is needed given we are copying (implicitly) via the painting into another surface

we can just p.drawImage(p_.data());
