225	This - Pointer to Graphics Output protocol instance\r
226	BltBuffer - The data to transfer to screen\r
227	BltOperation - The operation to perform\r
228	SourceX - The X coordinate of the source for BltOperation\r
229	SourceY - The Y coordinate of the source for BltOperation\r
230	DestinationX - The X coordinate of the destination for BltOperation\r
231	DestinationY - The Y coordinate of the destination for BltOperation\r
232	Width - The width of a rectangle in the blt rectangle in pixels\r
233	Height - The height of a rectangle in the blt rectangle in pixels\r
234	Delta - Not used for EfiBltVideoFill and EfiBltVideoToVideo operation.\r
235	If a Delta of 0 is used, the entire BltBuffer will be operated on.\r
