   The key width and number of groups associated with a key  are  used  to
   form a small two-dimensional array of KeySyms for a key. This array may
   be different sizes for different keys. The array for a  single  key  is
   stored  as a linear list, in row-major order. The arrays for all of the
   keys are stored in the syms field of the client map. There is  one  row
   for each group associated with a key and one column for each level. The
   index corresponding to a given group and shift level is computed as:

        idx = group_index * key_width + shift_level

   The offset field of the key_sym_map entry for a key is used  to  access
   the beginning of the array.

   XkbKeyGroupsWidth  computes  the  maximum width associated with the key
   corresponding to keycode.
