+      (DestinationX + Width, DestinationY + Height).

+      Only one pixel will be used from the BltBuffer. Delta is NOT used.

+      (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.

+      (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

+      to the video display rectangle (DestinationX, DestinationY)

+      (DestinationX + Width, DestinationY + Height).

+     The BltBuffer and Delta  are not used in this mode.

+    SourceX       - X coordinate of source for the BltBuffer.

+    SourceY       - Y coordinate of source for the BltBuffer.

+    DestinationX  - X coordinate of destination for the BltBuffer.

+    Height        - Hight of rectangle in BltBuffer in pixels.

+    Delta         -
