// 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... // |
