    	Set visual depth to 24 for 32 bits-per-pixel devices on
    	Win32. This allows gdk_drawable_real_draw_pixbuf() to use the
    	optimized composite_0888() function rather than the slower image
    	dithering functions to draw pixbufs (#313993, John Ehresman)
    
    	* gdk/win32/gdkimage-win32.c (_gdk_win32_new_image): Use
    	_gdk_windowing_get_bits_for_depth() to initialize
    	GdkImage::bits_per_pixel.
    	(_gdk_windowing_get_bits_for_depth): Return 32 bits for depth 24.
    
    	* gdk/win32/gdkpixmap-win32.c (gdk_pixmap_new): Use
    	_gdk_windowing_get_bits_for_depth() to initialize
    	BITMAPINFOHEADER::biBitCount.
    
    	* gdk/win32/gdkvisual-win32.c (_gdk_visual_init): Set
    	GdkVisual::depth to 24 even if GetDeviceCaps(BITSPIXEL) returns
    	32.
