 * The Direct3DDevice is NOT the parent of the WineD3DDevice, because d3d

    /* Note about D3DRENDERSTATE_TEXTUREMAPBLEND implementation: most of values
    for this state can be directly mapped to texture stage colorop and alphaop, but
    D3DTBLEND_MODULATE is tricky: it uses alpha from texture when available and alpha
    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,
    unless some broken game will be found that cares. */
