    	Apply the same fixes and improvements as to the
    	gtk-1-3-win32-production branch: Bug fixes and cleanup of
    	selection and DND functionality. Still doesn't work as well as the
    	win32-production branch, though, but getting closer.
    
    	After this, need to add Archaeopteryx Software's OLE2 DND support.
    
    	* gdk/win32/gdkselection-win32.c (gdk_selection_owner_set,
    	gdk_selection_send_notify, generate_selection_notify): Don't use
    	SendMessage() to generate events for the same app, instead use
    	gdk_event_put().
    
    	* gdk/win32/gdkprivate-win32.h
    	* gdk/win32/gdkglobals-win32.c
    	* gdk/win32/gdkmain-win32.c
    	* gdk/win32/gdkevents-win32.c: Thus, remove declaration, definition,
    	initialisation and handling of gdk_selection_notify_msg,
    	gdk_selection_request_msg and gdk_selection_clear_msg.
    
    	* gdk/win32/gdkselection-win32.c (gdk_text_property_to_text_list,
    	gdk_free_text_list, gdk_string_to_compound_text,
    	gdk_free_compound_text): Implement trivially, witrh a text_list
    	always having a single element, and a compound text always
    	consisting of just a single (UTF-8!) string. Let's see how well
    	this works.
    
    	* gdk/win32/gdkselection-win32.c (gdk_selection_convert): Fix
    	non-ASCII paste from the clipboard: Try getting the same formats
    	from the Windows clipboard that gdk_property_change() puts there:
    	CF_UNICODETEXT, UTF8_STRING or CF_TEXT+CF_LOCALE.
    
    	* gdk/win32/gdkproperty-win32.c (gdk_property_change): When
    	storing text on the clipboard, handle non-ASCII text
    	correctly. The logic is as follows:
    
    	If we have only ASCII characters, use CF_TEXT.
    
    	Else, if we are on NT, use CF_UNICODETEXT.
    
    	Else (we are on Win9x), if all the characters are present in the
    	code page of some installed locale, use CF_TEXT and also set
    	CF_LOCALE to that locale.
    
    	Else (still on Win9x) store as RTF. We use a very simple RTF
    	string, just the text, no fonts or other crap, with the non-ASCII
    	characters as Unicode \uN keywords. Additionally, also store the
    	UTF-8 string as such, under the format "UTF8_STRING", so that GDK
    	can also paste from the Clipboard what it has copied there. (Thus
    	no need to implement any RTF parser.)
    
    	(find_common_locale): New function, implements the search for a
    	locale for case 3 above.
    
    	* gdk/win32/gdkglobals-win32.c: New global variables
    	compound_text, text_uri_list, utf8_string, cf_rtf and
    	cf_utf8_string.
    
    	* gdk/win32/gdkim-win32.c (_gdk_ucs2_to_utf8): New function,
    	converts from a wchar_t string to UTF-8.
    	(_gdk_utf8_to_ucs2): Rename from _gdk_win32_nmbstowchar_ts.
    	(_gdk_utf8_to_wcs): Rename from gdk_nmbstowchar_ts.
    
    	* gdk/win32/gdkevents-win32.c (build_keypress_event): Use
    	_gdk_ucs2_to_utf8().
    
    	* gdk/win32/gdkselection-win32.c: Remove some unnecessary logging.
    
    	* gdk/win32/gdkdnd-win32.c: Plug memory leaks, the
    	gdk_drag_context_ref() was called unnecessarily in a couple of
    	places, meaning drag contexts were never freed. The same memory
    	leaks seem to be present in gdk/linux-fb/gdkselection-fb.c, BTW.
    
    	(gdk_drop_reply): For WIN32_DROPFILES drops, free the temporarily
    	stored file list.
    
    	* gdk/win32/gdkselection-win32.c: Clarify the use of the
    	sel_prop_table. Now it is used only for storing the GDK_SELECTION
    	"properties".
    
    	The file names dropped with WM_DROPFILES -style DND is stored
    	temporarily (between the drop and the target picking them up) in a
    	separate place.
    
    	Have a separate hash table to map selection atoms to owner
    	windows. This used to be quite mixed up.
    
    	(_gdk_dropfiles_store): New function, to store the dropped file
    	list for the drop target to possibly fetch, and clear it
    	afterwards, from gdk_drop_reply().
    
    	(gdk_selection_owner_get): Much simplified now.
