Better test for visible desktop, should be working on all platforms.

[Jakob Eriksson]

I took this test from the gdi32 conformance tests, since it fails
reliably when run under a non visible desktop, regardless of platform.


It's not pretty, but I don't have an NT4 to test with, so I didn't want 
to change
anything. Later I can refactor it into exactly the failing part.


regards,
Jakob Eriksson
