Implement proper decorationless popups by specifying the type of the child window with with_type()

With this PR different kind of child windows can be created

  • Popups: Special windows without any decoration which can be positioned relative to the parent
  • Window: Normal window with a parent or not

The type can be specified during creation of the Window using the window_attributes and the with_type() function. As default a normal Window is used. If Popup is choosen a parent must be specified, otherwise the Popup creation fails with an Error returned by the new() function.

Reason: Because a normal window can have a parent window as well, like a Dialog
Reason: otherwise the child surface is anchored to the center
Reason: otherwise the height of the client side decoration is not considered and therefore the location is shifted
Reason: There are multiple pointers to the smithay popup. Once in state.windows and one time in the popup object it self. Just dropping the popup object releases only one pointer but we have to notify the state to release also the other
…he position

Reason: Much easier in the resize handle
Reason: we have to call resize to initialize the viewport to map to correct window size
