IME for Japanese / 日本語入力(IME)について

---

以下のNim言語コンパイル / リンク時オプションを加えることで日本語入力を可能としている
オプションはバックエンドのC/C++コンパイラにのみ渡される

--passc:"-DIMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS"
--passL:"-limm32"

同じことをconfig.nims内に記述する場合は以下となる

switch "passC","-DIMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS"
switch "passL","-limm32"
