// XFont.cpp Version 1.1
//
// Author: Philip Patrick (GetFontProperties)
//
// Version 1.0 - Initial release of GetFontProperties()
//
// Modified by: Hans Dietrich
// hdietrich2@hotmail.com
//
// Version 1.1: - Removed MFC dependency from GetFontProperties()
// - Converted CFile file I/O to memory mapped file
// - Added Unicode support
// - Combined with my GetFontFile() routine
