Tor Lillqvist 0b2ac32cf5 New debugging function, to log a clipboard format name symbolically.
2005-04-04  Tor Lillqvist  <tml@novell.com>

	* gdk/win32/gdkmain.c (_gdk_win32_cf_to_string): New debugging
	function, to log a clipboard format name symbolically.
	(_gdk_win32_data_to_string): Also new, to log random data bytes.

	Implement delayed rendering on Win32, specifically for transfering
	images through the clipboard from GTK+ apps to other
	apps (#168173, implementation by Ivan Wong):

	* gdk/win32/gdkevents-win32.c (gdk_event_translate):
	Handle WM_RENDERFORMAT.

	* gdk/win32/gdkprivate-win32.h
	* gdk/win32/gdkglobals-win32.c: Add _format_atom_table,
	_delayed_rendering_data and _image_bmp.

	* gdk/win32/gdkmain-win32.c: Initialize _image_bmp.

	* gdk/win32/gdkproperty-win32.c (gdk_property_change):
	Accept formats other than GDK_TARGET_STRING or _utf8_string, and
	assume they are handled through delayed rendering.

	* gdk/win32/gdkselection-win32.c (gdk_selection_convert):
	Return all available formats (including those registered by GTK+
	apps) on request_targets.
	(gdk_selection_property_get): We should append a zero byte like
	X11 does.
	(gdk_win32_selection_add_targets): New function, for
	gtkselection's use. Win32 requires that the clipboard owner
	registers all valid formats even if the owner wants delayed
	rendering.
	(_gdk_win32_selection_convert_to_dib): New function. Convert
	images to DIB using gdk-pixbuf.

	* gdk/win32/gdkwin32.h: Declare gdk_win32_selection_add_targets().

	* gtk/gtkselection.c (gtk_selection_add_target,
	gtk_selection_add_targets): Call gdk_win32_selection_add_targets()
	to register target formats.

	* gdk/gdk.symbols: Add gdk_win32_selection_add_targets().
