* @class AIWindowDraggingView
* @brief This NSView subclass makes the window move when it is dragged by the view itself (but not by subviews).
*
* The code is, for reference, a stripped down version of the code powering AIBorderlessWindow's dragging movements.
*
* On mouse down, the window's frame is noted; deltas as the mouse moves are used to determine the window's
* own movements.
