It is likely that Alexandre was waiting for an OK from me or Henri. He is the 
only committer, but when someone he doesn't know sends a patch he usually 
waits for the OK from someone who is maintaining the part of Wine. I think I 
forgot to send an OK mail to the test when you submitted it.

A few minor suggestions for the test:
* The vertex structure should be declared somewhere else already, as part of 
the lighting test I think. You can reuse that instead of redeclaring it.

* You don't have to AND the color if 0xffffff, getPixelColor should do that 
already.

* You don't have to set the render states unless you need a different setting 
than the previous tests leave behind

* The "if(hr == D3D_OK)" after BeginScene should be changed 
to "if(SUCCEEDED(hr))"
