	* gdk/win32/gdkcursor-win32.c (pixbuf_to_hbitmaps_alpha_winxp):
	Rename the variables for the color bitmap to have "color" in their
	name, for similarity with pixbuf_to_hbitmaps_normal(). Create a
	color bitmap for the mask, too, instead of creating a b&w bitmap
	with CreateBitmap(). Set up the mask bitmap's contents, ones for
	those pixels in the color bitmap where the alpha is zero, zero for
	other pixels. We used to use an unitialized mask bitmap! This
	meant that icons and cursors created presumably worked more or
	less by accident. Totally blank icons with zero alpha everywhere
	(as used by gtktrayicon.c) definitely did not work as expected.
