    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.
