Can we make border width zero by default?

Can we make border width zero by default?

Hello.

While looking into bug 5848, I experimented with border width (not internal 
border width).  The default is currently 2 pixels.  I'd like to set that to zero.

The reasons are that some window managers (metacity at least) overrides this 
and sets zero anyway.  Other window managers like compiz make the border on 
two sides transparent and black on the other two.  Probably this is some 
effect applications can take advantage of, but for Emacs it just looks strange 
(see screen shot).

For the Gtk+ port, border width has no effect, it can't be specified in 
Gtk+-functions and it is hardcoded to 0 in the Gtk+ code.

Any thoughts?

Fine by me (for the trunk).  I don't know the reasoning behind the
current 2px default.

It was/is used to mark the frame with the focus.  The focused frame gets a 
black border, the rest a gray border.
