Test for window messages of a property sheet with custom dialog proc (bug 12104)

[Bernhard Übelacker]

Hello,
the attached patch consists of a test case for following bug:
http://bugs.winehq.org/show_bug.cgi?id=12104

This test shows how cygwin's setup checks if a WM_SIZE message
was received (by the custom window proc).

In wine only the property page gets such a message - not the sheet.

If I got it right, tests which would fail in wine are prefixed with todo_wine?

I want to ask if this patch looks right for inclusion and if the
location (dlls/comctl32/tests/) is right?

Kind regards,
Bernhard
