Here are the implementations of those functions I did for ReactOS. (and no,
I didnt use disassembler on them this time :)
I am licencing them under whatever licence I need to in order for them to
go into WINE (if the WINE team wants them that is)
They compile on ReactOS just fine. Not sure if they work or not, tests
would be usefull :)

RECT r;
HBRUSH hBrush;

}

}
BTW, I can also share some of the info I have on other user32 functions I
was able to figure out/find info on if there is a need for it.
