+/** 

+  This protocol provides a basic abstraction to set video modes and 

+  copy pixels to and from the graphics controller's frame buffer. 

+

+  @par Protocol Description:

+  The EFI_UGA_DRAW_PROTOCOL provides a software abstraction to allow pixels to be drawn

+  directly to the frame buffer. The EFI_UGA_DRAW_PROTOCOL is designed to be lightweight and

+  to support the basic needs of graphics output prior to Operating System boot.  

+

+  @param GetMode 

+  Returns information about the geometry and configuration of the

+  graphics controller's current frame buffer configuration.

+

+  @param SetMode 

+  Set the graphics device into a given mode and clears the frame buffer to black.

+

+  @param Blt 

+  Software abstraction to draw on the video device's frame buffer.
