Correct the appearance of non-square icons and cursors: pad them to square
2006-04-06 Tor Lillqvist <tml@novell.com> Correct the appearance of non-square icons and cursors: pad them to square so that Windows won't stretch them. * gdk/win32/gdkcursor-win32.c (create_alpha_bitmap) (create_color_bitmap): Always create square bitmaps, take only side length as argument. (pixbuf_to_hbitmaps_alpha_winxp, pixbuf_to_hbitmaps_normal): Corresponding changes.
