Well, that patch by Iulian does work in wine-0.9.22 (it does redraw properly),
I'm attaching it (apply it by "cd wine-0.9.22; patch -p1 < dirty_rectangle.patch").

It makes Heroes 4 slightly faster (the sound doesn't skip any more when you move
the mouse around the map / minimap, but it does skip when you scroll the map as
a whole).

But it's still very buggy, notably winecfg crashes when you go to the "Audio"
tab. wine needs a proper DIB engine, a dirty rectangle hack won't help much.
