FRAME must be a live frame and defaults to the selected one. The return
value is an association list of the attributes listed below. All height

`outer-position' is a cons of the outer left and top edges of FRAME
relative to the origin - the position (0, 0) - of FRAME's display.
`outer-size' is a cons of the outer width and height of FRAME. The
outer size includes the title bar and the external borders as well as
any menu and/or tool bar of frame.
`external-border-size' is a cons of the horizontal and vertical width of
FRAME's external borders as supplied by the window manager.
`title-bar-size' is a cons of the width and height of the title bar of
FRAME as supplied by the window manager. If both of them are zero,
FRAME has no title bar. If only the width is zero, Emacs was not
able to retrieve the width information.
`menu-bar-external', if non-nil, means the menu bar is external (never
included in the inner edges of FRAME).
`menu-bar-size' is a cons of the width and height of the menu bar of
FRAME.
`tool-bar-external', if non-nil, means the tool bar is external (never
included in the inner edges of FRAME).
`tool-bar-position' tells on which side the tool bar on FRAME is and can
be one of `left', `top', `right' or `bottom'. If this is nil, FRAME
has no tool bar.
`tool-bar-size' is a cons of the width and height of the tool bar of
FRAME.
