Here is Sho's comment:

     "2. Square cells

     Each cell of the map (dice table) should be square so that a user
     can easily see symmetry of the table. Rectangular cells skew this
     symmetry, and make it harder for a user to grasp characteristics of
     the position.

     Displaying equity numbers and best moves are very nice features,
     but because visuality is the key of this TempMap method, symmetry
     of a map has higher priority, in my opinion.

     Here's my suggestion: By default, a map doesn't display equity
     numbers or best moves, and each cell is square. When a user choose
     to display them, then gnubg widens all cells so numbers fit in."

yes, that's possible:

(a) save the widgets for the gtk_aspect_frame_new
(b) new check button: 

    when active:

       gtk_aspect_frame_set( GTK_ASPECT_FRAME( ... ),
                             0.5, 0.5, 1.0, FALSE );

    when inactive

       gtk_aspect_frame_set( GTK_ASPECT_FRAME( ... ),
                             0.5, 0.5, 1.0, TRUE );


I suppose that should work.

gtk_drawing_area_set_size

but that indicates only the minimum size. GTK may make the height, the
width, or both larger. By setting homogeneous=TRUE for the surrounding
GtkTable and by putting the table into a GtkAspectFrame I forced the
square-ness.
