/**
Prints a formatted Unicode string to a graphics console device specified by
ConsoleOutputHandle defined in the EFI_SYSTEM_TABLE at the given (X,Y) coordinates.
This function prints a formatted Unicode string to the graphics console device
specified by ConsoleOutputHandle in EFI_SYSTEM_TABLE and returns the number of
Unicode characters printed. If the length of the formatted Unicode string is
greater than PcdUefiLibMaxPrintBufferSize, then only the first
PcdUefiLibMaxPrintBufferSize characters are printed. The EFI_HII_FONT_PROTOCOL
is used to convert the string to a bitmap using the glyphs registered with the
HII database. No wrapping is performed, so any portions of the string the fall
outside the active display region will not be displayed.
If a graphics console device is not associated with the ConsoleOutputHandle
defined in the EFI_SYSTEM_TABLE then no string is printed, and 0 is returned.
If the EFI_HII_FONT_PROTOCOL is not present in the handle database, then no
string is printed, and 0 is returned.
If Format is NULL, then ASSERT().
If Format is not aligned on a 16-bit boundary, then ASSERT().
@param X X coordinate to print the string.
@param Y Y coordinate to print the string.
@param ForeGround The forground color of the string being printed. This is
an optional parameter that may be NULL. If it is NULL,
then the foreground color of the current ConOut device
in the EFI_SYSTEM_TABLE is used.
@param BackGround The background color of the string being printed. This is
an optional parameter that may be NULL. If it is NULL,
then the background color of the current ConOut device

@param Format Null-terminated Unicode format string. See Print Library
