interactive-adjust-move in pasteboard%

This method is called during an interactive move (for each selected snip) to preprocess the user-determined snip location for each selected snip. The snip and mouse-determined locations (in editor coordinates) are passed into the method (boxed); the resulting locations are used for graphical feedback to the user during moving.

The actual mouse coordinates are first sent through interactive-adjust-mouse before determining the locations passed into this method.
