/**
 * adjust_frame_size:
 *
 * Adjust size of frame F.  NEW_WIDTH and NEW_HEIGHT specify the new
 * text size of F in pixels.  A value of -1 means no change is requested
 * for that direction (but the frame may still have to be resized to
 * accommodate windows with their minimum sizes).  This can either issue
 * a request to resize the frame externally (via x_set_window_size), to
 * resize the frame internally (via resize_frame_windows) or do nothing
 * at all.
 *
 * The argument INHIBIT can assume the following values:
 *
 * 0 means to unconditionally call x_set_window_size even if sizes
 *   apparently do not change.  Fx_create_frame uses this to pass the
 *   initial size to the window manager.
 *
 * 1 means to call x_set_window_size if the native frame size really
 *   changes.  Fset_frame_size, Fset_frame_height, ... use this.
 *
 * 2 means to call x_set_window_size provided frame_inhibit_resize
 *   allows it.  The menu and tool bar code use this ("3" won't work
 *   here in general because menu and tool bar are often not counted in
 *   the frame's text height).
 *
 * 3 means call x_set_window_size if window minimum sizes must be
 *   preserved or frame_inhibit_resize allows it.  x_set_left_fringe,
 *   x_set_scroll_bar_width, x_new_font ... use (or should use) this.
 *
 * 4 means call x_set_window_size only if window minimum sizes must be
 *   preserved.  x_set_right_divider_width, x_set_border_width and the
 *   code responsible for wrapping the tool bar use this.
 *
 * 5 means to never call x_set_window_size.  change_frame_size uses
 *   this.
 *
 * Note that even when x_set_window_size is not called, individual
 * windows may have to be resized (via `window--sanitize-window-sizes')
 * in order to support minimum size constraints.
 *
 * PRETEND is as for change_frame_size.  PARAMETER, if non-nil, is the
 * symbol of the parameter changed (like `menu-bar-lines', `font', ...).
 * This is passed on to frame_inhibit_resize to let the latter decide on
 * a case-by-case basis whether the frame may be resized externally.
