void OverSample( const DXOVERSAMPLEDESC *pOverDesc );

No return value.
This method does not modify the current position of the pointer object.
DXSurface implementations are optimized for opaque colors (alpha = 255). In these cases, this operation is identical to a sample replacement and no blending is done.
