Emacs already accepts that message (see w32term.c), but currently does nothing with it except announcing the change to the attached debugger. However, on Windows the message also specifies the new resolution, so this:
Technically the incoming x11 event does too, but as you can re-query with the existing #'display-pixel-width etc. functions (and get the new values) anyway by the time the hook actually runs (on x11), wasn't sure we needed to allow for propagation of the info really.
