Is GtkIMContext a GObject or a GtkObject?

[Jeff Franks <jcf tpg com au>]

I just noticed this discrepency:

In the 1.3.10's Changelog the following new entries appear:

> Fri Oct 19 18:35:22 2001  Manish Singh  <yosh gimp org>
>
>   * gtk/{gtkentry.c,gtktextview.c}: since GtkIMContext derives directly
>    from GObject now, we have to use the g_object_* functions, not
>    gtk_object_*.

and

>Fri Oct 19 15:08:30 2001  Owen Taylor  <otaylor redhat com>
>
>    * gtk/{gtkimcontext.c,gtkimcontextsimple.c,gtkimmulticontext.c}
>    modules/input/{gtkimcontextxim.c,imcyrillic-translit.c,iminuktitut.c,
>    imipa.c,imthai-broken.c,imviqr.c}: Make GtkIMContext derive from
>    GObject, not GtkObject. (#62621)

but in gtkimcontext.h GtkIMContext still derives directly from 
GtkObject. Is this an oversight?
