Associates an ID3DXTextureGutterHelper object with the ID3DXPRTBuffer object.
HRESULT AttachGH( LPD3DXTEXTUREGUTTERHELPER pGH );
If the method succeeds, the return value is D3D_OK.
The reference count of the ID3DXTextureGutterHelper object will automatically be incremented by one. Any existing ID3DXTextureGutterHelper pointers will be released.
You must ensure that the number of ID3DXPRTBuffer::AttachGH calls matches the number of ID3DXPRTBuffer::ReleaseGH calls. After calling ID3DXPRTBuffer::ReleaseGH, the pGH pointer returned by ID3DXPRTBuffer::AttachGH should no longer be used.
