However, when I checked it against the mode line by dragging the tool
bar down to it, I found that this has changed since my previous build
(from 2006-01-05): now detaching the tool bar collapses it to a single
button, which when clicked expands the tool bar (with smaller icons)
vertically. Is this due to the following change?

* gtkutil.c (update_frame_tool_bar): Use new tool bar functions
(gtk_toolbar_insert) so we can have tool bars of different sizes.
If so, maybe it should be mentioned in News, since the behavior is
quite different: previously the detached tool bar remained expanded
and horizontal, now it is only vertical (when expanded), and smaller.
