bug#25408: Remove Decorations Around Emacs Frame (Windows OS)

[martin rudalics]

I now installed most of the changes from my earlier patch.  Minor
changes for an `internal-border' face, `x-focus-frame' and
`select-window' will follow.  Also a major documentation rewrite will be
installed in the next days.  Till then, the major purpose of installing
was to check whether we get any breakage of existing code.

If people can see anything fishy, please report immediately.  Affected
might be among others scroll bars, frame deletion and selection.  Also,
most of the new parameters won't work on NS.  Hopefully, Alan or Anders
can help us with some of them.

Did you try that in the meantime?

For X I have now also provided an `override-redirect' parameter which
should replicate what the tooltip code does.  If you still get
animations then I think you will have to explicitly tell the WM (for
example, via the frame title) to turn them off.
