Proposed GtkTreeViewColumn API change

[Jonathan Blandford <jrb redhat com>]

While this is a little late, I'd like to make a small API change to
GtkTreeViewColumn.  It effects a very few people who currently
explicitly set their mode to be RESIZABLE.  Currently, it has a
GtkTreeViewColumnSizing enum to determine how sizing is done.  This is
defines as:

typedef enum
{
  GTK_TREE_VIEW_COLUMN_GROW_ONLY,
  GTK_TREE_VIEW_COLUMN_RESIZABLE,
  GTK_TREE_VIEW_COLUMN_AUTOSIZE,
  GTK_TREE_VIEW_COLUMN_FIXED
} GtkTreeViewColumnSizing;

It was pointed out that RESIZABLE is identical to GROW_ONLY in
functionality, with the exception that it's user resizable, and that
FIXED could also be user resizable.  Rather than add FIXED_RESIZABLE to
the enum, I'd rather make resizable a property, and remove it from the
enum.  Additionally, if I add another sizing mode for 2.2, I would have
to add 2 variants (one for resizing).

So, which should I do:

1) Add GTK_TREE_VIEW_COLUMN_FIXED_RESIZABLE
2) Remove GTK_TREE_VIEW_COLUMN_RESIZABLE and add a "::resizable"
   property[*]
3) Nothing
4) Some other solution I haven't considered

I'm currently leaning towards option 2.   Anyone else have comments?
Thanks,

[*] The property would not work, of course, for GTK_TREE_VIEW_COLUMN_AUTOSIZE
