    	* gdk/win32/*.c: Massive changes. Too many to list here, but I'll
    	try a summary:
    	1) Unify GdkPixmap and GdkImage implementation: For each
    	GdkPixmap, allocate a GdkImage, and vice versa.
    	GdkPixmapImplWin32Data has a pointer to the GdkImage.
    	GdkImage::windowing_data is a pointer to the GdkPixmap.
    	This simplifies many pixmap and image related functions a lot, and
    	reduces duplicated code snippets. For instance, there is only one
    	place in gdk/win32 where CreateDIBSection() is called, in the
    	function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap)
    	to a Windows region is almost trivial, with the bitmap bits being
    	readily accessible in the associated GdkImage.
    	All blitting between GdkPixmaps, GdkWindows and GdkImages goes
    	through handled the _gdk_win32_blit() function, which calls
    	different functions to handle the cases of blitting from pixmaps,
    	inside windows (scrolling), or from windows, which all require
    	somewhat different handling.
    	2) Support 256-color mode. This has long been very broken, now it
    	works more or less OK. Keep the logical palette for each colormap
    	as small as possible while allocating and freeing colors. Select
    	and realize the logical palette associated with a GdkColormap into
    	a DC before drawing or blitting.
    	When the display is in 256-color mode, make it possible for the
    	user to override the size of the palette(s) used with either the
    	GDK_WIN32_MAX_COLORS environment variable, or a -max-colors
    	command line option. It is possible to reduce the palette size all
    	the way down to using just the 16 static colors (which causes the
    	system visual to be of type GDK_VISUAL_STATIC_COLOR. This could
    	possibly be useful if one desperately wants to avoid color
    	flashing. (Note that in order for this to work properly, an as of
    	yet not commited fix to gdkrgb.c is needed.)
    	Handle the palette messages. On WM_PALETTECHANGED, call
    	UpdateColors() for the given window hierarchy. Do this only if a
    	window in some other top-level window hierarchy caused the palette
    	change (realized a palette). Do this max five times in a row (an
    	arbitrarily chosen limit), though, otherwise redraw by generating
    	expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole
    	window hierarchy by generating GDK_EXPOSE events.
    	3) Code cleanup in general. For instance, remove the "emulated"
    	X11 structs ColormapStruct, Visual and XStandardColormap. Use the
    	new GDK_DEBUG_* flags for debugging output in the relevant source
    	files. Remove the unused colormap hash table in gdkcolor-win32.c
    	4) Plug some resource leaks.

    	* gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use
    	g_filename_to_uri() to actually create legal URIs in the
    	text/uri-list data.
