	* gdk/win32/gdkcolor-win32.c
	* gdk/win32/gdkscreen-win32.c
	* gdk/win32/gdkwindow-win32.c: Whitespace consistency
	fixes. Remove superfluous test for GdkWindow* parameters being
	non-NULL. Testing GDK_IS_WINDOW() is enough. As there is only one
	GdkScreen and one GdkDisplay in the Win32 backend, use those
	variables instead of the getter functions. For GdkDisplay* and
	GdkScreen* parameters, check that they are equal to the
	corresponding singleton variables instead of the more general
	GDK_IS_DISPLAY() or GDK_IS_SCREEN().
