  directly to every pixel of the video display rectangle 
  (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). 
  Only one pixel will be used from the BltBuffer. Delta is NOT used.

  <B>EfiBltVideoToBltBuffer</B> - Read data from the video display rectangle 
  (SourceX, SourceY) (SourceX + Width, SourceY + Height) and place it in 
  the BltBuffer rectangle (DestinationX, DestinationY ) 
  (DestinationX + Width, DestinationY + Height). If DestinationX or 
  DestinationY is not zero then Delta must be set to the length in bytes 
  of a row in the BltBuffer.

  <B>EfiBltBufferToVideo</B> - Write data from the  BltBuffer rectangle 
  (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the 
  video display rectangle (DestinationX, DestinationY) 
  (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is 
  not zero then Delta must be set to the length in bytes of a row in the 
  BltBuffer.

  <B>EfiBltVideoToVideo</B> - Copy from the video display rectangle (SourceX, SourceY)
  (SourceX + Width, SourceY + Height) .to the video display rectangle 
  (DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height). 
  The BltBuffer and Delta  are not used in this mode.

  @param  This         Protocol instance pointer.
  @param  BltBuffer    Buffer containing data to blit into video buffer. This
                       buffer has a size of Width*Height*sizeof(EFI_GRAPHICS_OUTPUT_BLT_PIXEL)
  @param  BltOperation Operation to perform on BlitBuffer and video memory
  @param  SourceX      X coordinate of source for the BltBuffer.
  @param  SourceY      Y coordinate of source for the BltBuffer.
  @param  DestinationX X coordinate of destination for the BltBuffer.
  @param  DestinationY Y coordinate of destination for the BltBuffer.
  @param  Width        Width of rectangle in BltBuffer in pixels.
  @param  Height       Hight of rectangle in BltBuffer in pixels.
  @param  Delta        OPTIONAL

  @retval EFI_SUCCESS           The Blt operation completed.
  @retval EFI_INVALID_PARAMETER BltOperation is not valid.
  @retval EFI_DEVICE_ERROR      A hardware error occured writting to the video buffer.
