Screenshots of the bug

It looks like Wine 1.1.33 do not render transparency in Rayman 2.

It seems to be a regression: it used to work with Wine 1.1.24, but Wine 1.1.25
broke it and no recent version of Wine (including the current last 1.1.33)
fixes that bug.

I attach some screenshots to this report that show the bug: the right side is
1.1.24 with a correct rendering (notice the text and transparent water and
transparent sparks) whereas the left side shows the rendering of version 1.1.25
to 1.1.33 (notice the squares replacing the text and non transparent water and
black shadows and non transparent sparks).

The configuration tool that comes with the game (wine GXSetup.exe) shows the
following information:
 - Renderer: "3 DirectX6 (1.0.0) DirectX 6 Driver"
 - Driver: "DirectDraw HAL (display)"
 - Device: "Wine D3DDevice using WineD3D and OpenGL (Direct3D HAL)"
selecting "RGB Direct3D emulation (Direct3D HEL)" for the Device do not "fix"
the bug.

I also attach the output of wine 1.1.33 when running Rayman2.exe.

Here is my configuration:
 - up to date Ubuntu Karmic Koala 9.10
 - NVidia GeForce FX 5600
 - up to date driver nvidia 173.14.20
