    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. */

 * IDirect3DDevice7::ComputeSphereVisibility
 *
 * Calculates the visibility of spheres in the current viewport. The spheres
 * are passed in the Centers and Radii arrays, the results are passed back
 * in the ReturnValues array. Return values are either completely visible,
 * partially visible or completely invisible.
 * The return value consist of a combination of D3DCLIP_* flags, or it's
 * 0 if the sphere is completely visible(according to the SDK, not checked)
 *
 * Sounds like an overdose of math ;)
 *
 * Version 3 and 7
 *
 * Params:
 *  Centers: Array containing the sphere centers
 *  Radii: Array containing the sphere radii
 *  NumSpheres: The number of centers and radii in the arrays
 *  Flags: Some flags
 *  ReturnValues: Array to write the results to
 *
 * Returns:
 *  D3D_OK because it's a stub
 *  (DDERR_INVALIDPARAMS if Centers, Radii or ReturnValues are NULL)
 *  (D3DERR_INVALIDMATRIX if the combined world, view and proj matrix
 *  is singular)

 * IDirect3DDeviceImpl_CreateHandle
 *
 * Not called from the VTable
 *
 * Some older interface versions operate with handles, which are basically
 * DWORDs which identify an interface, for example
 * IDirect3DDevice::SetRenderState with DIRECT3DRENDERSTATE_TEXTUREHANDLE
 *
 * Those handle could be just casts to the interface pointers or vice versa,
 * but that is not 64 bit safe and would mean blindly derefering a DWORD
 * passed by the app. Instead there is a dynamic array in the device which
 * keeps a DWORD to pointer information and a type for the handle.
 *
 * Basically this array only grows, when a handle is freed its pointer is
 * just set to NULL. There will be much more reads from the array than
 * insertion operations, so a dynamic array is fine.
 *
 * Params:
 *  This: D3DDevice implementation for which this handle should be created
 *
 * Returns:
 *  A free handle on success
 *  0 on failure
 *
