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:
ImageHandle - The driver image handle of the caller. The parameter is used to
optimize the loading of the image file so that the FV from which
the driver image is loaded will be tried first.
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
