  Routine Description:\r
    The following table defines actions for BltOperations:\r
    EfiUgaVideoFill - Write data from the  BltBuffer pixel (SourceX, SourceY) \r
      directly to every pixel of the video display rectangle \r
      (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). \r
      Only one pixel will be used from the BltBuffer. Delta is NOT used.\r
    EfiUgaVideoToBltBuffer - Read data from the video display rectangle \r
      (SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in \r
      the BltBuffer rectangle (DestinationX, DestinationY ) \r
      (DestinationX + Width, DestinationY + Height). If DestinationX or \r
      DestinationY is not zero then Delta must be set to the length in bytes \r
      of a row in the BltBuffer.\r
    EfiUgaBltBufferToVideo - Write data from the  BltBuffer rectangle \r
      (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the \r
      video display rectangle (DestinationX, DestinationY) \r
      (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is \r
      not zero then Delta must be set to the length in bytes of a row in the \r
      BltBuffer.\r
    EfiUgaVideoToVideo - Copy from the video display rectangle (SourceX, SourceY)\r
     (SourceX + Width, SourceY + Height) .to the video display rectangle \r
     (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). \r
     The BltBuffer and Delta  are not used in this mode.\r
\r
  Arguments:\r
    This          - Protocol instance pointer.\r
    BltBuffer     - Buffer containing data to blit into video buffer. This \r
                    buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)\r
    BltOperation  - Operation to perform on BlitBuffer and video memory\r
    SourceX       - X coordinate of source for the BltBuffer.\r
    SourceY       - Y coordinate of source for the BltBuffer.\r
    DestinationX  - X coordinate of destination for the BltBuffer.\r
    DestinationY  - Y coordinate of destination for the BltBuffer.\r
    Width         - Width of rectangle in BltBuffer in pixels.\r
    Height        - Hight of rectangle in BltBuffer in pixels.\r
    Delta         -\r
  \r
  Returns:\r
    EFI_SUCCESS           - The Blt operation completed.\r
    EFI_INVALID_PARAMETER - BltOperation is not valid.\r
    EFI_DEVICE_ERROR      - A hardware error occured writting to the video \r
                             buffer.\r
