* 2/12/2015 jichi: SystemAoi5
*
* Note that BUNNYBLACK 3 also has SystemAoi5 version 4.1
*
* Hooked to PgsvTd.dll for all SystemAoi engine, which contains GDI functions.
* - Old: AoiLib.dll from DrawTextExA
* - SystemAoi4: Aoi4.dll from DrawTextExW
* - SystemAoi5: Aoi5.dll from GetGlyphOutlineW
*
* Logic:
* - Find GDI function (DrawTextExW, etc.) used to paint text in PgsvTd.dll
* - Then search the function call stack, to find where the exe module invoke PgsvTd
* - Finally insert to the call address, and text is on the top of the stack.
