 * IDirect3DDevice implementation, version 1, 2, 3 and 7. Rendering is relayed
 * to WineD3D, some minimal DirectDraw specific management is handled here.
 * The Direct3DDevice is NOT the parent of the WineD3DDevice, because d3d
 * is initialized when DirectDraw creates the primary surface.
 * Some type management is necessary, because some D3D types changed between
 * D3D7 and D3D9.

    from diffuse otherwise. So changing the texture must be monitored in SetTexture to modify
    alphaarg when needed.
 
    Aliens vs Predator 1 depends on accurate D3DTBLEND_MODULATE emulation
 
    Legacy texture blending (TEXTUREMAPBLEND) and texture stage states: directx6 docs state that
    TEXTUREMAPBLEND is deprecated, yet can still be used. Games must not use both or results
    are undefined. D3DTBLEND_MODULATE mode in particular is dependent on texture pixel format and
    requires fixup of stage 0 texture states when texture changes, but this fixup can interfere
    with games not using this deprecated state. So a flag 'legacyTextureBlending' has to be kept
    in device - TRUE if the app is using TEXTUREMAPBLEND.
 
    Tests show that setting TEXTUREMAPBLEND on native doesn't seem to change values returned by
    GetTextureStageState and vice versa. Not so on Wine, but it is 'undefined' anyway so, probably, ok,
