Returns:
NULL or a pointer to the LibClipart gallery instance
Notes: The bars system always keeps one LibClipart gallery alive for us. If one is not found, this usually indicates that it can't be found in bars.ini: Check that the 'Name' string *exactly* matches the title string given in bars.ini. Also check that bars.ini indicates the bar is of the LibClipartSGallery class
