Extended Surface Capabilities

Beginning with Microsoft DirectX 6.0, Microsoft DirectDraw contains surface capabilities beyond those found in previous versions. These extended capabilities require the addition of several new structures, specifically the DDSCAPS2 and DD_MORESURFACECAPS structures. The DDSCAPS2 structure contains the dwCaps member originally found in the DDSCAPS structure, but also contains three new members: dwCaps2, dwCaps3, and dwCaps4. Only dwCaps2 is used in DirectDraw for DirectX 6.0. The last three members of the DDSCAPS2 structure are also identically arranged in the DDSCAPSEX structure.
