XkbComputeSectionBounds - Update the bounding box of a section

geom   geometry that contains the section

       section
              section to be examined and updated

        If  you  add  or  delete a row to or from a section, or if you change the geometry of any of the rows in
       that section, you may need to update the bounding box for that section.

       XkbComputeSectionBounds examines all the rows of the section and updates the bounding box of that section
       so that it contains all rows.  XkbComputeSectionBounds returns False if any of  the  arguments  is  NULL;
       otherwise, it returns True.
