Options

(Fx_create_frame): Rename menuBarLines resource to menuBar. 

(x_figure_window_size): Decode (- N), (+ N) for position.
(x_set_frame_parameters): Handle (+ N) and (- N).
Preserve negative positions properly too.
[USE_X_TOOLKIT] (x_window): Let xneg, yneg specify whether to
negate left and top.
(Fx_parse_geometry): Handle [XY]Negative with positive number
or negative number without [XY]Negative.
