/*++
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

/*++
Routine Description:
Convert a *.BMP graphics image to a UGA blt buffer. If a NULL UgaBlt buffer
is passed in a UgaBlt buffer will be allocated by this routine. If a UgaBlt
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.
UgaBltSize will contain the required size.
