// 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... //
