Star Trek: Starfleet Academy - missing textures and flickering backgrounds

[WinterSnowfall]

The game has a D3D executable, which uses D3D3. Doesn't appear to work all that well with D7VK however. Menus/animations don't all work properly when overlayed on 3D scenes, and all the 3D objects are missing their textures.

The situation is somewhat better since 274c6e5, however some surface overlay dirties/overlap is still there.
