// 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.
//
// Input: 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
//
// Output: 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.
// EFI_OUT_OF_RESOURCES - No enough buffer to allocate
