This method retrieves a texture assigned to a stage for a device.
HRESULT GetTexture( DWORD Stage, IDirect3DMobileBaseTexture** ppTexture );
[in] Stage identifier of the texture to retrieve. Stage identifiers are zero-based. The maximum number of texture stage states is defined in D3DM_TEXSTAGECOUNT and the number of texture stages supported by the device is in D3DMCAPS as MaxTextureBlendStages.
[out] Address of a pointer to an IDirect3DMobileBaseTexture interface that represents the returned texture.
Calling this method will increase the internal reference count on the IDirect3DMobileTexture interface. Failure to call IUnknown::Release when finished using this IDirect3DMobileTexture interface results in a memory leak.
