// 初期化 / ウィンドウ管理系 API の動作確認用サンプル。アセット不要。
//
// 確認対象:
//   init(WindowConfig{..})   advance_frame   delta_time   elapsed_time
//   set_window_position/window_position   set_window_size/window_size
//   set_screen_size/screen_size   show_cursor   MAIN_SCREEN
//
// WindowConfig の transparent/topmost/decorations/resizable/vsync は
// 初期化時にしか切り替えられないため、下の定数を書き換えて再実行して確認する。
