If this option is nil, setting font, menu bar, tool bar, tab bar,
internal borders, fringes or scroll bars of a specific frame may resize
the frame in order to preserve the number of columns or lines it
displays. If this option is t, no such resizing happens once a frame
has got its initial size. If this is the symbol `force', no implicit
resizing happens whenever a new frame is made. This can be useful with
tiling window managers where the initial size of a frame is determined
by external means.
displays.
If this option is t, no such resizing happens once Emacs has agreed with
the window manager on the final initial size of a frame. That size will
have taken into account the size of the text area requested by the user
and the size of all decorations initially present on the frame.
If this is the symbol `force', no implicit resizing happens even before
a frame has obtained its final initial size. As a consequence, the
initial frame size may not necessarily be the one requested by the user.
This value can be useful with tiling window managers where the initial
size of a frame is determined by external means.
The value of this option can be also a list of frame parameters. In
this case, resizing is inhibited when changing a parameter that
appears in that list. The parameters currently handled by this option
include `font', `font-backend', `internal-border-width',
`menu-bar-lines', `tool-bar-lines' and `tab-bar-lines'.
