【Directx9游戏汉化 #9】来世(nextlife) 字幕显示函数

本游戏采用了CEGUI,该组件能采用directx和opengl。
经过我的小方块测试，游戏屏幕显示了小方块，因此确认是directx9的游戏。
游戏自带一个EngineSetup.exe程序，设置为窗口模式后就能用cheatengine调式。
（由于游戏窗口较大，我将游戏屏幕和cheatengine分别显示到2个显示器上即可。）

在游戏中找一个字幕，在以下地方断下。
由于该游戏基本都是显示在屏幕固定位置（上或者下，居中），
因此暂时认为此处就是游戏的字幕函数，该函数被20处左右地方调用。

NextLife.exe+11C5 - 42 - inc edx
! o: _ X2 n: B/ C# E
