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.

(DestinationX, DestinationY) (DestinationX + Width, DestinationY + Height).

Blt a rectangle of pixels on the graphics screen. Blt stands for BLock Transfer.

Set the video device into the specified mode and clears the visible portions
