+ Routine Description:
+ The following table defines actions for BltOperations:
+ EfiUgaVideoFill - Write data from the BltBuffer pixel (SourceX, SourceY)
+ 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.
+ EfiUgaVideoToBltBuffer - 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.
+ EfiUgaBltBufferToVideo - 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.
+ EfiUgaVideoToVideo - 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.
+
+ Arguments:
+ This - Protocol instance pointer.
+ BltBuffer - Buffer containing data to blit into video buffer. This
+ buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
+ BltOperation - Operation to perform on BlitBuffer and video memory
+ SourceX - X coordinate of source for the BltBuffer.
+ SourceY - Y coordinate of source for the BltBuffer.
+ DestinationX - X coordinate of destination for the BltBuffer.
+ DestinationY - Y coordinate of destination for the BltBuffer.
+ Width - Width of rectangle in BltBuffer in pixels.
+ Height - Hight of rectangle in BltBuffer in pixels.
+ Delta -
+
+ Returns:
+ EFI_SUCCESS - The Blt operation completed.
+ EFI_INVALID_PARAMETER - BltOperation is not valid.
+ EFI_DEVICE_ERROR - A hardware error occured writting to the video
