// ======================================================================================
// FastFormatAscii / FastFormatUnicode (overview!)
// ======================================================================================
// Fast formatting of ASCII or Unicode text. These classes uses a series of thread-local
// format buffers that are allocated only once and grown to accommodate string formatting
// needs. Because the buffers are thread-local, no thread synch objects are required in
// order to format strings, allowing for multi-threaded string formatting operations to be
// performed with maximum efficiency. This class also reduces the overhead typically required
// to allocate string buffers off the heap.
//
// Drawbacks:
// * Some overhead is added to the creation and destruction of threads, however since thread
// construction is a typically slow process, and often avoided to begin with, this should
// be a sound trade-off.
//
// Notes:
// * conversion to wxString requires a heap allocation.
// * FastFormatUnicode can accept either UTF8 or UTF16/32 (wchar_t) input, but FastFormatAscii
// accepts Ascii/UTF8 only.
