I'd suggest to add the tests not only for various parameters passed
to CreateIconFromResourceEx (not just a random one), but also add to
the resources icons/images with different color depth and test how they
are loaded (for instance the bug 10854 mentions an app which has 24-bpp
bitmap or icon in its resources, and that leads to the problem later
on when the app usess the returned handle to draw an image).
