+Routine Description:
+
+ Return the graphics image file named FileNameGuid into Image and return it's
+ size in ImageSize. All Firmware Volumes (FV) in the system are searched for the
+ file name.
+
+Arguments:
+
+ FileNameGuid - File Name of graphics file in the FV(s).
+
+ Image - Pointer to pointer to return graphics image. If NULL, a
+ buffer will be allocated.
+
+ ImageSize - Size of the graphics Image in bytes. Zero if no image found.
+
+
+Returns:
+
+ EFI_SUCCESS - Image and ImageSize are valid.
+ EFI_BUFFER_TOO_SMALL - Image not big enough. ImageSize has required size
+ EFI_NOT_FOUND - FileNameGuid not found

+ buffer is passed in it will be used if it is big enough.
+
+Arguments:
+
+ BmpImage - Pointer to BMP file
+
+ BmpImageSize - Number of bytes in BmpImage
+
+ UgaBlt - Buffer containing UGA version of BmpImage.
+
+ UgaBltSize - Size of UgaBlt in bytes.
+
+ PixelHeight - Height of UgaBlt/BmpImage in pixels
+
+ PixelWidth - Width of UgaBlt/BmpImage in pixels
+
+
+Returns:
+
+ EFI_SUCCESS - UgaBlt and UgaBltSize are returned.
+ EFI_UNSUPPORTED - BmpImage is not a valid *.BMP image
+ EFI_BUFFER_TOO_SMALL - The passed in UgaBlt buffer is not big enough.
