//  I've stopped keeping track, there are far too many reasons already to    //
//  hate Microsoft. Anyway, this class keeps track of various Win32 fonts we //
//  allocate because Win98/ME seems to have problems re-allocating the exact //
//  same freaking goddamn font over and over again. I mean, you'd think      //
//  there'd be a rule somewhere about deterministic behavior when calling    //
//  the exact same function with the exact same parameters over and over...  //
//  Oh, wait...                                                              //
