Re: frame parameters user-size and user-position

[Richard Stallman]

    I don't see `user-size' documented anywhere (e.g. Info (elisp)), but I see
    it used in these files: faces.el, frame.el, mac-win.el, w32-win.el,
    x-win.el, and frame.c. If it is similar to `user-position', shouldn't it be
    documented?

Thanks.  I will document it.

    Would it be possible (after the release) to have Emacs update these frame
    parameters whenever a user repositioned or resized a frame (e.g. using the
    mouse)? That is, could we perhaps use these parameters to _indicate_ whether
    the user has repositioned or resized a frame (even if the indication is not
    100% reliable)?

It might be a good idea, but we can think about it later.
