We have made quite some progress towards that goal in 2.6, with hi-level
api to handle text, images and uris:

void           gtk_target_list_add_text_targets  (GtkTargetList  *list,
						  guint           info);
void           gtk_target_list_add_image_targets (GtkTargetList  *list,
						  guint           info,
						  gboolean        writable);
void           gtk_target_list_add_uri_targets   (GtkTargetList  *list,
						  guint           info);

gboolean gtk_selection_data_set_text (GtkSelectionData
*selection_data,
				      const gchar          *str,
				      gint                  len);
guchar * gtk_selection_data_get_text (GtkSelectionData
*selection_data);
gboolean gtk_selection_data_set_pixbuf   (GtkSelectionData
*selection_data,
				          GdkPixbuf         *pixbuf);
GdkPixbuf *gtk_selection_data_get_pixbuf (GtkSelectionData
*selection_data);
gboolean gtk_selection_data_set_uris (GtkSelectionData
*selection_data,
				      gchar               **uris);
gchar  **gtk_selection_data_get_uris (GtkSelectionData
*selection_data);

void           gtk_drag_dest_add_text_targets  (GtkWidget    *widget);
void           gtk_drag_dest_add_image_targets (GtkWidget    *widget);
void           gtk_drag_dest_add_uri_targets   (GtkWidget    *widget);

void           gtk_drag_source_add_text_targets  (GtkWidget
*widget);
void           gtk_drag_source_add_image_targets (GtkWidget    *widget);
void           gtk_drag_source_add_uri_targets   (GtkWidget    *widget);
