Referencing reactos as a source of the information makes it unlikely
to improve the chances of including the patch in Wine. Moreover, as
was already discussed many times, theme interface is completely
undocumented and different between Windows versions, therefore it's
very unlikely that there is an application that depends on the
details of this interface, thus making it unnecessary to duplicate
it in Wine.
