/********************************************************************************************
ShinaRio hook:
Game folder contains rio.ini.
Problem of default hook GetTextExtentPoint32A is that the text repeat one time.
But KF just can't resolve the issue. ShinaRio engine always perform integrity check.
So it's very difficult to insert a hook into the game module. Freaka suggests to refine
the default hook by adding split parameter on the stack. So far there is 2 different
version of ShinaRio engine that needs different split parameter. Seems this value is
fixed to the last stack frame. We just navigate to the entry. There should be a
sub esp,* instruction. This value plus 4 is just the offset we need.
New ShinaRio engine (>=2.48) uses different approach.

* Sample game: 幻創のイデア (RIO 2.49)
* Text painted by GetGlyphOutlineA.
* Debugged by attaching to GetTextExtentPoint32A.
* There is only one GetTextExtentPoint32A in the game, where only 'Y' (0x59) is calculated.
* Text is in a large memory region that can be modified.
*
* When the text contains new line (_r), the same text will be invoked twice.
* Need to avoid immediate duplicate.
