This hook is invoked during an interactive resize. \n\ It is called with seven arguments, WINDOW, X-POSITION, Y-POSITION,\n\ NEW-WIDTH-PIXELS, NEW-HEIGHT-PIXELS, NEW-WIDTH-UNITS, and\n\ NEW-HEIGHT-UNITS whenever the window is changed to a new size. The\n\ first five arguments refer to the size and position of the frame\n\ window (not the client window). The -UNITS arguments refer to the size\n\ of the client window and are in client units (e.g., characters for\n\ Emacsen and XTerms).
