/*
  FreeTypeに文字幅、太字、斜体をキャッシュする機構が無いのでそれらを補う

  1. まずDllMain(DLL_PROCESS_ATTACH)でFreeTypeFontEngineのインスタンスが生成される。
     (順番はCGdiPPSettings→FontLInit(FreeType)→FreeTypeFontEngine→フック)
     ForceChangeFontもここで処理する。

  2. CreateFontでFreeTypeFontEngine::AddFontが呼び出され、FreeTypeFontInfoと
     フォント名を結びつける。
     ついでにFreeTypeFontInfoはIndividualの設定をコピーして持つ。

  3. ExtTextOutやGetTextExtentなどからFreeTypePrepare関数が呼び出されると
     さらに内部でFreeTypeFontInfo::GetCacheが呼び出され、フォントサイズなどから
     FreeTypeFontCacheを得る。無ければ生成する。
     FreeTypeFontCacheは内部にFreeTypeCharDataのテーブル(UCS2なので2^16個)を
     持っていて、FreeTypeCharDataには文字毎にキャッシュデータを保管する。

  4. FreeTypeFontCacheから、文字またはグリフ番号を元にFreeTypeCharDataを得る。
     キャッシュがあれば(メモリ中に残っていれば)、MRUカウンタをセットする。
     無い場合は一旦スルーし、後でAddCharDataでキャッシュを追加する。

  5. 追加しまくるとメモリを喰らうので、追加が一定数(FREETYPE_REQCOUNTMAX)を超えると
     GCモドキで最近参照されたキャッシュデータをFREETYPE_GC_COUNTER個だけ残し、
     それ以外のデータ(FreeTypeCharData)は開放される。
     この2つの定数はiniで設定変更できた方がいいような気もする。

  6. 最後に、DllMain(DLL_PROCESS_DETACH)でFreeTypeFontEngineのインスタンスが破棄され、
     全てのキャッシュメモリが開放される。
