/**
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.
