// Notes
// ---------------------------------------------------------------------------
// * This library is still under development.
// * Please see http://www.cs.colorado.edu/~main/bgi for information on
// * using this library with the mingw32 g++ compiler.
// * This library only works with Windows API level 4.0 and higher (Windows 95, NT 4.0 and newer)
// * This library may not be compatible with 64-bit versions of Windows
