I have code to do this elsewhere - I will post next time I am at the
right PC.  I think there are a couple of things to test for: Whether
the window is top-level or not, and whether the window is visible or
not.  Possibly some other things too.

Most (but not all) methods that can be invoked on window objects can
also be called with a window object or a window handle as a first
argument:

my $v = $win->IsVisible();

or

my $v = Win32::GUI::IsVisible($win);
my $v = Win32::GUI::IsVisible($hwnd);
