-

-  This file implements the EFI 1.1 Device Driver model requirements for UGA

-

-  UGA is short hand for Universal Graphics Abstraction protocol.

-

-  This file is a verision of UgaIo the uses UnixThunk system calls as an IO 

-  abstraction. For a PCI device UnixIo would be replaced with

-  a PCI IO abstraction that abstracted a specific PCI device.

-  Since the window information is processed in an other thread we need
-  a keyboard Queue to pass data about. The Simple Text In code just
-  takes data off the Queue. The WinProc message loop takes keyboard input
-  and places it in the Queue.

-
-  Routine Description:
-    Blt pixels from the rectangle (Width X Height) formed by the BltBuffer
-    onto the graphics screen starting a location (X, Y). (0, 0) is defined as
-    the upper left hand side of the screen. (X, Y) can be outside of the
-    current screen geometry and the BltBuffer will be cliped when it is
-    displayed. X and Y can be negative or positive. If Width or Height is
-    bigger than the current video screen the image will be clipped.
-
-  Arguments:
-    This          - Protocol instance pointer.
-    X             - X location on graphics screen.
-    Y             - Y location on the graphics screen.
-    Width         - Width of BltBuffer.
-    Height        - Hight of BltBuffer
-    BltOperation  - Operation to perform on BltBuffer and video memory
-    BltBuffer     - Buffer containing data to blt into video buffer. This
-                    buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
-    SourceX       - If the BltOperation is a EfiCopyBlt this is the source
-                    of the copy. For other BLT operations this argument is not
-                    used.
-    SourceX       - If the BltOperation is a EfiCopyBlt this is the source
-                    of the copy. For other BLT operations this argument is not
-                    used.
-
-  Returns:
-    EFI_SUCCESS           - The palette is updated with PaletteArray.
-    EFI_INVALID_PARAMETER - BltOperation is not valid.
-    EFI_DEVICE_ERROR      - A hardware error occured writting to the video
-                             buffer.
