HI_TDE2_EndJob：提交添加操作完成的TDE 任务。

HI_TDE2_QuickCopy：向任务中添加快速拷贝操作。

HI_TDE2_QuickFill：向任务中添加快速填充操作。

HI_TDE2_QuickResize：向任务中添加光栅位图缩放操作。

HI_TDE2_QuickDeflicker：向任务中添加抗闪烁操作。

HI_TDE2_Bitblit：向任务中添加对光栅位图进行有附加功能的搬移操作。

HI_TDE2_MbBlit：向任务中添加对宏块位图进行有附加功能的搬移操作。

HI_TDE2_SolidDraw：向任务中添加对光栅位图进行有附加操作的填充搬移操作。

HI_TDE2_BitmapMaskRop：向任务中添加对光栅位图进行Mask Rop 搬移操作。

HI_TDE_BitmapMaskBlend：向任务中添加对光栅位图进行Mask Blend 搬移操作。

HI_TDE2_Osd2Mb：向任务中添加将光栅格式数据叠加到宏块位图的操作。

HI_TDE2_CancelJob：取消指定的TDE 任务。

HI_TDE2_WaitForDone：等待指定的TDE 任务完成。
