 28.4.4 Geometry
 ---------------
 
 Here’s how to examine the data in an X-style window geometry
 specification:
 
  -- Function: x-parse-geometry geom
      The function ‘x-parse-geometry’ converts a standard X window
      geometry string to an alist that you can use as part of the
      argument to ‘make-frame’.
 
      The alist describes which parameters were specified in GEOM, and
      gives the values specified for them.  Each element looks like
      ‘(PARAMETER . VALUE)’.  The possible PARAMETER values are ‘left’,
      ‘top’, ‘width’, and ‘height’.
 
      For the size parameters, the value must be an integer.  The
      position parameter names ‘left’ and ‘top’ are not totally accurate,
      because some values indicate the position of the right or bottom
      edges instead.  The VALUE possibilities for the position parameters
      are: an integer, a list ‘(+ POS)’, or a list ‘(- POS)’; as
      previously described (Position Parameters).
 
      Here is an example:
 
           (x-parse-geometry "35x70+0-0")
                ⇒ ((height . 70) (width . 35)
                    (top - 0) (left . 0))
