	* gdk/win32/gdkcursor-win32.c: As there is only one GdkDisplay in
	the Win32 backend, check that GdkDisplay* parameters are equal to
	_gdk_display instead of using the unnecessarily general
	GDK_IS_DISPLAY().

* 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.
* gtk/Makefile.am: Include gtkstatusicon.c on all platforms.
