For example, with the `inverse-video' face attribute, like we do for the
`mode-line' face.

The toolbar is represented by a propertized string created by
`build_desired_tool_bar_string'.  It is only the frame parameter
`tool_bar_window' that mandates one toolbar per frame.

It could be created by the same means as the header-line window.
