Well, I don't know if it's currently still used on windows, but according to
my tests it still works. You can use that function to make comctl32 register
one of its classes, for example "Combobox" as "6.0.7601.17514!Combobox".
The other ways I found to make comctl32 register its classes (all of them at
once) is to call GetClassInfoExW or CreateWindowExW with windows class
WC_BUTTONW/WC_COMBOBOXW/etc. Don't know that internally works though, just
loading the library is not enough for it to register its classes, somehow
comctl32 needs to be told when to register its classes.
Is it a bad idea to use this function for this purpose? AFAIK it's introduced
after XP, and is used to register the redirected classes. Correct me if I'm
wrong though.
Honestly, I'm not sure if they want custom dlls to export such a function, but
it might be possible it's used in comctl32. I'll try to make an own side-by-
side dll to test that.
