I managed to fix half of the problem. With the patch I attached, we can start
the game with D3D, there are still glitches like on this screenshot however:


(the green stuff around some objects)

it would seem they are related to one HUGE commit, namely this:

commit c8901d6f6253f6c97610eb1068ac4ff89758ed0a
Author: Stefan Dösinger <stefandoesinger at gmx.at>

    ddraw: Rewrite most of ddraw using WineD3D.

Unfortunately, this commit is old, and because of the size (41000 lines of
code) it is very hard to know where exactly problem lays.

I think that those glitches are related to transparency of some objects, which
is not handled correctly (it was before rewrite - the graphics are perfect with
wine-0.9.15), but since I'm not a developer I can't really tell...

Hopefully someone will look at this, since it worked with older wine versions
it should be fairly easy to fix. And then we would have another PLATINUM title
in database :)
