The DirectDraw HEL supports the creation of texture, mipmap, and z-buffer surfaces. Furthermore, because of the tight integration of DirectDraw and Direct3D, a DirectDraw-enabled system always provides Direct3D support (in software emulation, at least). Therefore, the DirectDraw HEL exports the DDSCAPS_3DDEVICE flag to indicate that a surface can be used for 3D rendering. DirectDraw drivers for hardware-accelerated 3D display cards export this capability to indicate the presence of hardware-accelerated 3D.
